DHA Magnetic Resonance Imaging Technologists - General Exam Info Sample Questions

A diagnostic imaging technique in which the patient is injected with radioactive glucose, and then images are taken of areas of the body where the high metabolic activity is occurring, is known as which of the following?





Correct Answer:
positron emission tomography.
the correct answer to the question is: positron emission tomography (pet).

positron emission tomography, commonly referred to as pet, is an advanced diagnostic imaging technique used primarily in the fields of neurology, oncology, and cardiology to observe metabolic processes in the body. this technique provides vital information about the physiological functioning of tissues and organs. pet is particularly useful in detecting cancer, monitoring cancer treatment, examining the effects of cardiovascular diseases, and studying brain abnormalities in patients with neurological disorders.

the process begins with the injection of a radiotracer, which typically involves a form of glucose known as fluorodeoxyglucose (fdg), tagged with a radioactive isotope. glucose is a major energy source for most cells in the body, and cells that are most active metabolically (such as cancer cells) will use glucose more rapidly than normal cells. after the injection, the patient waits for approximately one hour to allow the radiotracer to distribute throughout the body and be absorbed by the tissues.

during the pet scan, the patient lies within a donut-shaped scanning machine. this machine detects the gamma rays emitted by the radiotracer. as the radiotracer decays, it emits positrons, which immediately collide with nearby electrons resulting in the emission of gamma rays. these gamma rays are then detected by the pet scanner. the scanner uses this information to create detailed, three-dimensional images of the tissues within the body. areas of high radiotracer uptake appear as bright spots on the pet images, indicating high metabolic activity.

the visualization of these bright spots helps physicians pinpoint areas of abnormal metabolic activity associated with disease. for example, in oncology, pet scans are crucial for detecting cancer metastases, or the spread of cancer to new areas, by identifying rapidly dividing cancer cells that consume glucose at a high rate. in neurology, pet helps in assessing brain functions and diagnosing conditions such as alzheimer's disease by observing cerebral glucose metabolism. in cardiology, pet can assess myocardial perfusion and viability, aiding in decisions regarding revascularization procedures.

overall, pet scans are a valuable tool in the diagnosis and management of various diseases, providing critical information that often cannot be obtained through other imaging techniques. the ability of pet to monitor the effectiveness of treatment also makes it an essential part of modern medical diagnostics, helping to tailor therapies to individual patients' needs and responses.

What type of artifact produces a difference in signal intensity across the imaging volume?





Correct Answer:
shading.


the correct answer to the question about what type of artifact produces a difference in signal intensity across the imaging volume is "shading."

shading, also known as intensity inhomogeneity, is a common artifact in magnetic resonance imaging (mri). it results in a non-uniform appearance of the image where certain areas appear darker or lighter compared to other areas within the same field of view. this can be caused by various factors including inhomogeneities in the main magnetic field, imperfections in the radiofrequency (rf) coils, or issues related to the rf penetration. the effect of shading can significantly impact the diagnostic quality of an mri scan by obscuring or altering the visibility of certain tissues or structures.

chemical shift artifact occurs due to differences in the resonance frequencies of fat and water protons. this artifact is characterized by a dark or bright edge at the interface between fat and water-containing tissues, and it does not cause a general difference in signal intensity across the imaging volume.

magnetic susceptibility artifact arises from variations in the magnetic properties of different materials in the body or from external sources. this leads to local distortions in the magnetic field, which can manifest as signal voids or geometric distortions in the image, particularly near metal implants or air-filled cavities.

truncation artifact, often referred to as gibbs artifact, occurs due to the limited number of frequencies used to reconstruct an image. this results in ringing or banding artifacts near the boundaries between high and low signal intensity areas, but it does not lead to a uniform change in signal intensity across the imaging volume.

in summary, while several types of artifacts can affect mri images, shading is specifically known for producing a difference in signal intensity across the imaging volume, potentially compromising the uniformity and accuracy of the diagnostic information obtained from the mri scan.
