Radiology Interview Questions & Answers - Learning Mode

Radiology represents a branch of medicine that deals with radiant energy in the diagnosis and treatment of diseases. This field can be divided into two broad areas ? diagnostic radiology and interventional radiology. A physician who specializes in radiology is called radiologist. Radiologists are medical doctors (MDs) or doctors of osteopathic medicine (DOs) who specialize in diagnosing and treating diseases and injuries using medical imaging techniques, such as x-rays, computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, positron emission tomography (PET) etc.

Question: What is a PET scan (positron emission tomography)?

Answer: A diagnostic imaging technique in which patients are given a special radioactive substance that emits positrons which in turn give rise to gamma rays which are detected by a gamma camera. Source:
Question: What is ultrasound?

Answer: Ultrasound consists of high frequency sound waves too high for the human ear to detect, rather like the noise used by bats and dolphins to determine where they are. These waves are emitted by an ultrasound probe and travel harmlessly through the body bouncing off various layers of tissue. The probe then hears these echoes which are relayed onto a screen allowing the pictures to be interpreted. Ultrasound is now the method of choice for monitoring the foetus during pregnancy and in diagnosis of n Source:
Question: What is a CAT or CT scan?

Answer: Computed axial tomography (CT scan) is simply another x-ray technique using a scanner that takes a series of pictures across the body allowing the radiologist to view the images in two dimensional or three dimensional form. Spiral CT is the most modern form of this imaging with the pictures being produced in only a few seconds. Source:
Question: What is magnetic resonance imaging (MRI)?

Answer: This test is similar to a CT scan but uses magnetism and radio waves to build up a series of cross sectional images. MRI pictures as so precise that they often provide as much information as directly looking at the tissues. For this reason MRI has potential to reduce the number of certain diagnostic procedures. MRI uses no x-rays and the magnetic fields are not known to be harmful. However, it takes longer to obtain the pictures than a conventional x-ray machine, and although the price is coming Source:
Question: During accommodation for near:
* a) The spherical aberration of the eye increases
* b) The ciliary muscle relaxes
* c) The field of vision decreases
* d) The amount of light entering the eye increases
* e) The thickness of the lens increases

Answer: a. F b. F c. T c. F e. T Source:
Question: What is fluoroscopy?

Answer: This machine produces a constant stream of x-rays so that it works in real time, enabling the doctor to view a changing image continuously, as in an interventional procedure. A digital unit produces an image where the picture elements (pixels) have a numerical value and this technology normally delivers a lower dose of radiation than the previous analogue system whilst providing high definition, high resolution images. Source:
Question: What is interventional radiology?

Answer: This encompasses any procedure that is invasive, usually involving the insertion of a needle, cannula (tube), catheter, or wire into the patient for diagnosis and /or treatment. Procedures include angioplasty (insertion of a balloon into a vein or artery to widen it and improve circulation), stenting (insertion of a tube to keep an artery or a vein open) and biopsies e.g. lung, breast, renal, liver, bone etc. Source:
Question: What is nuclear medicine or isotope scanning?

Answer: Radioisotopes give out a very small amount of radiation that can be detected by a specially designed sensitive type of camera. When a radioisotope is linked with certain chemicals it can, harmlessly, trace the workings of the human body. These tests allow radiologists to find alterations in the normal functioning of the body organs, for examples the heart of kidneys, or show early involvement of the body with infections or cancer. The dose of radiation given is very small, but following some tes Source:
Question: How safe are x-rays?

Answer: The risks associated with medical x-rays are frequently exaggerated. It is estimated that the chances of contracting cancer as a result of an x-ray of the chest, for example, are similar to the risks of contracting cancer by inhaling the smoke of one cigarette - about one in a million.

If you are worried about any treatment or scans you may be having, speak again to your GP or the hospital staff. They can refer to your medical records and if they know of your concerns they will always mak Source:
Question: What is a mammography?

Answer: The technique of using x-rays of the breast to detect irregularities or early signs of cancer. Source:
