Radiology Exam Questions and Answers

Understanding the physics of the above instruments is very much essential, for those connected with radiological sciences. It helps not only the education, but also the equipment selection, its optimal use, maintenance, and safety. Hence, an attempt is made to explain the physical principle, instrumentation, function, its application and limitations in the form of a single book. Attempt is also made to incorporate nuclear imaging and radiological safety in the same book. Large numbers of figures...

Introduction(+everything you need to know about breast imaging):  X-Rays was discovered by Wilhelm Conrad Röntgen on 8 November 1895.  Electromagnetic spectrum:  Photons that propagate in vacuum in straight lines at the speed of light; (Gamma ray → X-ray → Ultraviolet → Visible light → Infrared → Microwaves → Radio-waves)  X-rays:  Uses: 1. X-ray crystallography. 2. Mammography.  Produced by energy conversion in the X-ray tube.  A diagnostic image is c...

Temporal lobe • Understanding language(Wernicke’s area) • Memory • Hearing • Sequencing and organization Ct artifacts • Artifacts are distortions or errors in the image that are unrelated to the object scanned. Most common artifacts in CT are: • Motion artifact • Streak artifacts(cauEPIDURAL HEMATOMA • An epidural hematoma is usually associated with a skull fracture, it often occurs when an impact fractures the calvarium. The fractured bone lacerates a dur...

Plain film x-ray is the most common diagnostic radiological modality used in hospitals today. They were first discovered and used for imaging purposes by Wilhelm Röntgen on 8th November 1895, when he took an image of his wife’s hand X-rays are a type of electromagnetic radiation (just like visible light). There are three criteria that must be met to allow electromagnetic radiation to be used for imaging purposes: Ability to create to the electromagnetic radiation at the wavelength requi...
