Summary
Technetium extravasation can cause temporary limb discoloration. This condition is non-vesicant and resolves spontaneously without treatment, reassuring patients and physicians.
Area of Science:
- Nuclear Medicine
- Radiopharmacy
Background:
- An 80-year-old woman experienced sudden, asymptomatic black-to-purple discoloration of her right limb.
- This discoloration occurred immediately before a thyroid gammagraphy procedure.
Purpose of the Study:
- To describe a case of technetium extravasation.
- To highlight the benign nature and spontaneous resolution of this event.
Main Methods:
- Intravenous administration of Technetium-99m pertechnetate.
- Clinical observation of lesion evolution and patient history.
- Diagnosis based on clinical presentation and patient's lack of cooperation during injection.
Main Results:
- The patient developed asymptomatic black-to-purple skin discoloration.
- Lesions resolved spontaneously within 15 days without complications.
- Technetium was identified as non-vesicant.
Conclusions:
- Technetium extravasation is a benign condition.
- Reassurance for patients and physicians regarding the non-vesicant nature of technetium.
- Spontaneous resolution necessitates no specific treatment.

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:28Imaging Studies for Cardiovascular System V: CT
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
