The image produced by this type of medical imaging, called a cholescintigram, is also known by other names depending on which radiotracer is used, such as HIDA scan, PIPIDA scan, DISIDA scan, or BrIDA scan. [1] [2] Cholescintigraphic scanning is a nuclear medicine procedure to evaluate the health and function of the gallbladder and biliary system.

SPECT image (bone tracer) of a mouse MIP Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1]
Non-contact thermography, thermographic imaging, or medical thermology is the field of thermography that uses infrared images of the human skin to assist in the diagnosis and treatment of medical conditions.
Physical movement of the patient (i.e. the inability of the person to stay still when the scan is being taken). This kind of motion causes a blur in the phase-encoded direction of the image. Periodic motion such as arterial pulsations, swallowing, breathing and peristalsis results in discrete and well-defined ghosts.
Typical indications include epiphora and dacryocystitis. [3]DSG allows quantification of tear turnover and drainage. [4] Various quantification models have been developed, which must account for the variable drainage of asymptomatic systems. [5]
Vascular scanners also work very quickly, scanning in less than a second. As they scan, they capture the unique pattern formed by veins as they branch through the hand. The retinal scanner is more reliable than the vascular scanner, but is less widely used because of its intrusive nature.
Gated SPECT is a nuclear medicine imaging technique, typically for the heart in myocardial perfusion imagery. [1] An electrocardiogram (ECG) guides the image acquisition, and the resulting set of single-photon emission computed tomography (SPECT) images shows the heart as it contracts over the interval from one R wave to the next.
