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.
Mebrofenin's fast hepatic excretion (t ½ =17 minutes) and high hepatic uptake (98.1%) can be attributed to the 3-bromo-2,4,6-trimethylphenyl moiety. [3] To be a good hepatobiliary imaging agent, the chemical structure of mebrofenin has to meet certain requirements: an organic ion with molecular weight between 300 and 1000
Nuclear medicine myocardial perfusion scan with thallium-201 for the rest images (bottom rows) and Tc-Sestamibi for the stress images (top rows). The nuclear medicine myocardial perfusion scan plays a pivotal role in the non-invasive evaluation of coronary artery disease. The study not only identifies patients with coronary artery disease; it ...

A gastric emptying study is a nuclear medicine study which provides an assessment of the stomach's ability to empty.It may be used if there are complications after gastric surgery, for gastric reflux, or suspected gastroparesis amongst other indications. [1]
All radioactivity of [18 F]FDG, both the 20% which is rapidly excreted in the first several hours of urine which is made after the exam, and the 80% which remains in the patient, decays with a half-life of 110 minutes (just under two hours). Thus, within 24 hours (13 half-lives after the injection), the radioactivity in the patient and in any ...
Fasting is an ancient tradition, having been practiced by many cultures and religions over centuries. [9] [13] [14]Therapeutic intermittent fasts for the treatment of obesity have been investigated since at least 1915, with a renewed interest in the medical community in the 1960s after Bloom and his colleagues published an "enthusiastic report". [15]
SeHCAT is a taurine-conjugated bile acid analog which was synthesized for use as a radiopharmaceutical to investigate in vivo the enterohepatic circulation of bile salts. [2] By incorporating the gamma-emitter 75 Se into the SeHCAT molecule, the retention in the body or the loss of this compound into the feces could be studied easily using a standard gamma camera, available in most clinical ...
