Magnetic Resonance Imaging (MRI)
Goal: Highly detailed anatomical images
What Does It Do?
• Strong magnetic field is applied,
causing the nuclei within the
patient’s body to rotate and align
– Scanner detects, records, and
combines the different rotating
fields into a single image
– Gradients in all directions are
combined to create a 3D image
• Strong contrast between different
soft tissues within body
• Better at producing images of
brain, muscles, heart, cancers
than CT or x-rays
• Applications
– Used to distinguish
pathological tissue from normal
tissue
– Comparable resolution, much
better contrast resolution
(between arbitrarily different
but not identical tissues) than
CT
• Advantages
– Harmless to patient
• What it uses
– Strong magnetic fields
– Non-ionizing radiation
Magnetic Resonance Imaging (MRI)
Terminology
Parameters of Image Acquisition
• TE = echo time
• TR = repetition time
• TI = inversion time
– Time between inversion and
excitation pulses
Edema
• Abnormal accumulation of
fluid beneath the skin or in
cavities of the body
• Caused by increased
secretion of fluid into the
interstitium or impaired
removal of fluid
Magnetic Resonance Imaging (MRI)
Basic Scans
T1-weighted MRI scan
• Highlights fat deposits
– Water = dark; fat = bright
• Good grey v. white matter
contrast
• Commonly run clinical scan
• Short TE; short TR
T2*-weighted MRI scan
• Gradient Echo (GRE) sequence
•
Additional loss over T2 decay
• Air/tissue boundaries
susceptible
• Increases contrast of specific
tissues
• Long TE; long TR
T2-weighted MRI scan
• Highlights fluids
– Fat = dark; water = light
• Good for imaging edema
• Heavily used for clinical scans
of cerebral spinal fluid
• Long TE; long TR
Spin density weighted MRI scan
• No contrast from either T1 or
T2 decay
• Uses spin echo (sometimes
gradient echo) sequences
• Short TE; long TR
Magnetic Resonance Imaging (MRI)
Specialized Scans
Diffusion MRI scan
•
•
Diffusion tensor imaging (DTI) enables diffusion to be
measured in multiple directions
Make brain maps of fiber directions
– Examine connectivity of different regions of brain
– Examine areas of neural degeneration and
demyelination
Fluid Attenuated Inversion Recovery (FLAIR)
•
•
•
•
Functional MRI (fMRI)
•
•
•
Measures signal changes in the brain due to changing
neural activity
Low resolution, rapid rate scans
BOLD (Blood-Oxygen-Level Dependent) effect
•
Increases in neural activity cause changes in MR
signals via T2* changes
•
Increased neural activity increases demand
for oxygen
•
Vascular system overcompensated, increasing
oxygenated hemoglobin
•
High resolution 3D maps of venous vasculature
within neural tissue
Inversion-recovery pulse sequence that nulls fluid
signals
– Free water = dark; edematous tissue = bright
Most sensitive way to evaluate brain for
demyelinating diseases
Carefully-selected TI allows signal from any
particular tissue to be suppressed
Conversion of T2-weighted sequence via additional
radio frequency pulse and manipulation of
magnetic gradients
Real-Time MRI
•
•
•
Continuous monitoring ("filming") of moving
objects in real time
Should help provide information about diseases
of the joints and heart
May make MRI examinations easier and more
comfortable for patients
Magnetic Resonance Imaging (MRI)
Medical Applications
Interventional Therapy
Radiation Therapy Simulation
• MRI images used to guide
minimally invasive procedures
both intraoperatively and
interactively
• No ferromagnetic instruments
used
• Some specialized systems
allow imaging concurrent with
surgery
•
– Usually, surgical procedure is
temporarily interrupted so MR
images can be acquired to
verify success/guide
subsequent surgical work
•
•
•
MRIs used to specifically locate
tumors within body in preparation
for radiation therapy treatments
Patient placed in specific,
reproducible, body position and
scanned
MRI system computes precise
location, shape and orientation of
the tumor mass, correcting for
spatial distortion inherent in the
system
Patient is marked/tattooed with
points that, when viewed in
specified, reproducible body
position, permit precise
triangulation for radiation therapy
Magnetic Resonance Imaging (MRI)
What is MRI Compatibility?
Safety Concerns
• MR-Safe = device or implant that
is completely non-magnetic, nonelectrically conductive, and nonRF reactive
•
– Titanium and its alloys
• MR-Conditional = device that is
safe, provided the safety
conditions are defined and
observed
• MR-Unsafe = objects that are
significantly ferromagnetic and
pose a clear and direct threat to
persons and equipment within
the magnet room
• Patients always asked for
complete information about all
implants prior to entering the
MRI suite
Radio frequency energy
–
•
Peripheral Nerve Stimulation
–
•
Appropriate ear protection is necessary for anyone inside
MRI scanner room during examination
Cryogens
–
–
•
Rapid switching on and off of the magnetic field gradients
may cause nerve stimulation
Acoustic noise
–
•
Powerful radio transmitter can heat the body to the point
of risk of hyperthermia in patients
Cryogenic (extremely cold) liquids enable superconducting
capabilities of the electromagnetic coils
MRI support rooms should be equipped with pressure
relief mechanisms and an exhaust fan in case of a quench
(shut-down of superconduction electromagnet)
Pregnancy
–
Increasingly important for diagnosing and monitoring
congenital defects of the fetus (no contrast agents used)
• Fetal tumors (primarily teratomas)
• Facilitating open fetal surgery
• Other fetal interventions
• Planning to safely deliver and treat babies whose
defects would otherwise be fatal

•
•
•
•
Patient fasts for 4 hours or more
Intravenous bolus (tracer) injected patient's arm
1-2 hours later, patient placed into PET-CT,
usually with arms at the sides or above the head
Automatic bed moves head first into the gantry,
first obtaining a topogram (whole body flat
sagittal section)
Operator uses PET-CT console to identify patient
and examination, selects the scanning
parameters and starts image acquisition period
Patient automatically moved head-first into CT
gantry, where x-ray tomogram is acquired
Patient automatically moved through PET
gantry, parallel to CT gantry; PET slices acquired
Software reconstructs/aligs PET and CT images
Whole body scan (mid-thigh to top of head)
takes 5-40 min
Positron Emission TomographyComputed Tomography (PET-CT)
Positron Emission Tomography
• Uses radionucleotide decay to
generate 3D image of functional
processes in the body
– Detects gamma rays emitted by a
positron-emitting radionucleotide
("tracer")
• Tracer enters patient's body via a
biologically active molecule
• FDG is a tracer used to display
metabolic activity of tissue in
terms of regional glucose uptake
– Computer analyzes
location/concentration of tracer
within patient to construct 3D
images
X-ray Computed Tomography
• Uses computer processed
tomography to generate 3D
images from a collection of
2D x-ray images taken
around a single axis of
rotation
– Tomography = imaging by
sections
– Supplements x-rays and
medical ultrasonaography
– Used in
preventative/screening
medicine

Ultrasound
What is Ultrasound?
Applications
•
•
•
Cyclic sound pressure with a frequency (20 kHz 200 MHz) greater than the upper limit of human
hearing (typically 20,000 hertz in healthy young
adults)
Uses many different fields to penetrate a medium
and measure the reflection signature or supply
focused energy
–
•
Diagnostic sonography (AKA ultrasonography) =
ultrasound-based diagnostic imaging technique used
to visualize subcutaneous body structures such as
tendons, muscles, joints, vessels and internal organs
for possible pathology or lesions)
•
–
–
This property is used by bats to locate prey while
hunting
Most well-known application is use in sonography
to image a fetus in a human womb
–
–
–
–
–
Reflection signature can reveal details about the inner
structure of the medium
•
Able to determine size, structure, and any
pathological lesions using real-time tomographic
images
Soft tissue imaging
Cardiac (heart)
Renal (kidney)
Hepatic (liver and gallblader)
Muscuko-skeletal (muscles, ligaments,
tendons)
Ophthalmic (eyes)
Superficial (just under the skin) structures
•
•
Ex: testicles, thyroid, salivary glands,
lymph nodes
Guiding interventional procedures in
real time
–
–
Fine needle aspiration/biopsy (FNA/NAB) =
diagnostic procedure
Biopsy of masses for cytology or histology
testing in breast, thyroid, liver, kidney,
lymph nodes, muscles, joints
Ultrasound
Obstetric Imaging
Emergency Ultrasound
•
•
Used to identify many conditions harmful to
both mother and fetus
–
•
Risk of leaving such conditions undiagnosed is far
greater than the small risk associated with
undergoing the actual US scan
•
–
Primary uses:
–
–
–
–
–
–
–
–
–
Assess gestational age
Confirm fetal viability
Determine location of fetus, intrauterine v.
ectopic (displaced anywhere besides uterine wall)
Check the location of the placenta in relation to
the cervix
Detect multiple pregnancies
Detect major physical abnormalities
Assess fetal growth for evidence of intrauterine
growth restriction (IUGR)
Check for fetal movement and heartbeat
Determine the sex of the baby
Specialized application by emergency
responders to guide immediate first aid care
Pros
–
–
–
•
Cons
–
–
–
•

well; particularly good at delineating interfaces
between solid and fluid-filled spaces
Renders "live" images, helps narrow down
problem area
Determines severity and sources of trauma
within region
Portable, narrowly-focused, easy to use
Cannot penetrate bone
Depth of penetration limited, especially in
obese patients
Operator-dependent (high skill needed for good
quality images and accurate diagnoses)
Scanning methodologies
–
Focused Assessment with Sonography for
Trauma (FAST)
•
•
–
Detects internal bodily fluid in between organs in
cases of blunt abdominal trauma
Screening test for blood around the heart or
abdominal organs after trauma
CARDIASOUND
•
Detects blockages/clots/penetrations of the heart
Ultrasound
Biomedical Applications
•
•
•
Detection of pelvic abnormalities, involving abdominal/vaginal/rectal US
Break calculi (stones formed in the body) into fragments small enough to
be passed without excessive difficulty via lithotripsy
Ablate tumors non-invasively via High Intensity Focused Ultrasound (HIFU)
–
•
•
•
•
Acoustic Targeted Drug Delivery (ATDD) = enhanced transportation of
molecules across specified tissues via high frequency ultrasound
(frequency: 1-10 MHz; sound intensity: 0-30 watts/cm2)
Cataract treatment via phacoemulsification (surgery in which the eye's
internal lens is emulsified with an ultrasonic handpiece and aspirated from
the eye; aspirated fluids replaced with balanced salt solution)
Low-intensity pulsed ultrasound used to stimulate bone and tooth
regeneration, disrupt blood-brain barrier for drug delivery
Ultrasound-guided sclerotherapy and endovenous laser treatment
–
–
•
Magnetic Resonance-Guided Focused Ultrasound (MRgFUS) = guided by
MRI, a lower frequency (250-2000 kHz) than medical diagnostic ultrasound
is applied in significantly higher time-averaged intensities
Ultrasound-guided sclerotherapy = ultrasound is used to visualize the
underlying vein, allowing the physician to deliver and monitor the injection
of the vein-shrinking drug
Endovenous Laser Treatment (ELT) = minimally-invasive ultrasound-guided
technique used to treat varicose veins with laser energy
•
An optical fiber is inserted into the vein to be treated, a laser
light is shone into the interior of that vein, causing the vein to
contract; optical fiber is slowly withdrawn
Elastography = non-invasive method in which stiffness or strain images of
soft tissue are used to detect and classify tumors
–
–
When a mechanical compression or vibration is applied, the tumor
deforms less than the surrounding tissue (strain in the tumor is less than
that in the surrounding tissue)
Elasticity can discern health from unhealthy tissue in specific
organs/growths
•
Ultrasound Identification (USID)
–
Real Time Locating System (RTLS) or Indoor
Positioning System (IPS)
•
RTLS = used to wirelessly track and identify the
location of objects in real time
–
•
•
IPS = network of devices used to wirelessly
locate objects or people inside a building
Nonlinear propagation effects
–
•
Does not include speed, direction, or
spatial orientation
US waves usually display nonlinear
propagation (distortion) due to their high
amplitude to wavelength ratio
Safety Concerns
–
–
–
–
Occupational exposure to ultrasound in
excess of 120 dB may lead to hearing loss
Exposure in excess of 155 dB may produce
heating effects harmful to the human body
Exposures above 180 dB may lead to death
Recommended to avoid routine use of
ultrasound scans in low risk pregnancies
