RADT 1030 Chapter 1 Questions and Answers Graded A+ What is the primary purpose of radiology in medicine? Radiology is used to diagnose and monitor medical conditions by producing images of the inside of the body using various techniques like X-rays, CT scans, MRIs, and ultrasounds. What are the common types of imaging techniques used in radiology? The most common imaging techniques include X-rays, CT (computed tomography) scans, MRI (magnetic resonance imaging), ultrasound, and nuc...

RADT 142 Unit 1 Questions and Answers Graded A+ What is the difference between diagnostic imaging and therapeutic radiology? Diagnostic imaging focuses on creating images for diagnosis, while therapeutic radiology (radiation therapy) is used to treat medical conditions, primarily cancer, by delivering targeted radiation to tumors. How does the ALARA principle apply to radiology? The ALARA (As Low As Reasonably Achievable) principle aims to minimize radiation exposure by using the l...

RADT 1010 Chapter 1 Questions and Answers Graded A+ How does an ultrasound work in radiology?
