Abstract
This series comprises of a quiz pertaining to the identification of salient and important anatomical structures and landmarks expected to be seen at a given level on the computed tomography (CT) image. The representative image is followed by a series of images showing examples of different commonly encountered pathological entities that can be seen at this level in a routine clinical practice. Readers are encouraged to identify highlighted anatomical structures and landmarks in all the images and appreciate how a given abnormality can alter the appearance of normal structures. It is expected that this series will help nuclear physicians in interpretation of the CT component of the single photon emission computed tomography (SPECT) and positron emission tomography (PET) studies.
