Questions
QUESTION 1 OF 36
What is the difference between MRI and MRA?
Correct Answer: MRI = Magnetic Resonance Imaging. CANNOT give you any information on blood
vessels, just structures and ventricles.
MRA = Magnetic Resonance Angiography - Can look at the blood vessels .. should be ordered if there's a
concern for an occlusion
Rationale: Magnetic Resonance Imaging (MRI) provides detailed anatomical images of soft tissues and organs by
utilizing magnetic fields and radio waves, but it does not directly visualize blood flow or vessels. Magnetic Resonance
Angiography (MRA) is a specialized MRI technique specifically designed to image blood vessels, making it the
appropriate modality when a concern for vascular occlusion exists. Therefore, MRA is ordered to assess blood flow and
identify blockages within the vasculature, a capability MRI alone lacks. This aligns with MRA = Magnetic Resonance
Angiography - Can look at the blood vessels .. should be ordered if there's a concern for an occlusion, MRI = Magnetic
Resonance Imaging. CANNOT give you any information on blood vessels and just structures and ventricles..
QUESTION 2 OF 36
What is a mammography?
Correct Answer: -x-ray imaging of the breast tissue for early signs of cancer. It is the only way to detect
microcalcifications
Rationale: Mammography is a specialized radiographic examination utilizing low-dose X-rays to visualize breast
tissue. Its primary diagnostic purpose is the early detection of breast cancer, and it is uniquely capable of identifying
microcalcifications, which can be an initial indicator of malignancy. This imaging modality plays a critical role in
screening and diagnostic workups for breast pathology. This aligns with -x-ray imaging of the breast tissue for early
signs of cancer. It is the only way to detect microcalcifications and x-ray.
