Radiology: Medical Imaging Quiz

Radiology and Medical Imaging

• Radiologists are responsible for interpreting medical images and communicating the findings to other physicians.
• The main purpose of radiology is to diagnose and treat diseases using medical imaging technologies.

Imaging Modalities

• Ultrasound is the imaging modality that does not use electromagnetic radiation.
• Interventional radiology is a subspecialty of radiology that involves using imaging guidance to perform minimally invasive procedures.

Nuclear Medicine

• The main difference between nuclear medicine scans and radiology is that nuclear medicine scans use small amounts of radioactive materials to diagnose and treat diseases.
• Positron Emission Tomography (PET) is a physiological imaging modality that measures the body's biological functions.
• Radiopharmaceuticals are typically administered intravenously in nuclear medicine imaging.
• The purpose of a SPECT (Single Photon Emission Computed Tomography) scan is to capture 3D images of the body's internal structures and functions.

Nuclear Medicine Imaging

• Nuclear medicine imaging uses radiopharmaceuticals to capture internal radiation emissions, providing diagnostic information about the body's functions and metabolic processes.
