Summary
Gallbladder visualization during extremity lymphoscintigraphy may occur in patients who have fasted. This finding, observed with Tc-99m sulfur colloid, suggests fasting impacts tracer distribution.
Area of Science:
- Nuclear Medicine
- Diagnostic Imaging
- Lymphatic System Imaging
Background:
- Lymphoscintigraphy is a key diagnostic tool for lymphatic system disorders.
- Gallbladder visualization is an uncommon finding in extremity lymphoscintigraphy.
Purpose of the Study:
- To investigate the occurrence and potential causes of gallbladder visualization during lower extremity lymphoscintigraphy.
Main Methods:
- Retrospective evaluation of 13 patients undergoing lower extremity lymphoscintigraphy.
- Tc-99m sulfur colloid was used, with early and 24-hour delayed imaging.
- Patient history, particularly regarding fasting, was considered.
Main Results:
- Three out of thirteen patients exhibited gallbladder tracer accumulation.
- This accumulation was transient, disappearing on delayed 24-hour images.
- Gallbladder activity was exclusively observed in patients with a history of fasting prior to the examination.
Conclusions:
- Patient fasting state is a potential cause for gallbladder visualization in extremity lymphoscintigraphy.
- This transient finding may represent normal physiological tracer uptake in the fasting gallbladder.
- Further studies are warranted to confirm the relationship between fasting and gallbladder visualization.

01:17Gallbladder
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
