An octreotide scan is a type of SPECT scintigraphy used to find carcinoid, pancreatic neuroendocrine tumors, and to localize sarcoidosis. It is also called somatostatin receptor scintigraphy (SRS). Octreotide , a drug similar to somatostatin , is radiolabeled with indium-111 , [ 1 ] and is injected into a vein and travels through the bloodstream.
A retrograde urethrography [1] is a routine radiologic procedure (most typically in males) used to image the integrity of the urethra. Hence a retrograde urethrogram is essential for diagnosis of urethral injury, or urethral stricture. [2] [3]
Gallium scan showing panda (A) and lambda (B) patterns, considered specific for sarcoidosis in the absence of histological confirmation. In the past, the gallium scan was the gold standard for lymphoma staging, until it was replaced by positron emission tomography (PET) using 18 F-fluorodeoxyglucose (FDG).
Aortography involves placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta.The procedure is known as an aortogram. The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen.
Edotreotide (USAN, also known as (DOTA 0-Phe 1-Tyr 3) octreotide, DOTA-TOC, DOTATOC) is a substance which, when bound to various radionuclides, is used in the treatment and diagnosis of certain types of cancer. [3] When used therapeutically it is an example of peptide receptor radionuclide therapy.
Ultrasound is non-invasive and does not involve radiation, unlike some methods of imaging of the urinary tract such as X-rays or CT scans. [2] It is usually painless. [2] It is safe in pregnancy. [1] Risks specific to the scan involve: Discomfort from the abdominal probe [1] Distress related to results that are reported
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.
Radioisotope renography is a form of medical imaging of the kidneys that uses radiolabelling.A renogram, which may also be known as a MAG3 scan, allows a nuclear medicine physician or a radiologist to visualize the kidneys and learn more about how they are functioning. [1]
