FDG-PET/CT Focal Uptake on an Ocular Prosthesis
Clinical Nuclear Medicine
|April 17, 2018
Summary
An unexpected increase in radiotracer uptake was observed in a patient's artificial eye during an FDG-PET/CT scan. Understanding prosthesis type and replacement timing is key for accurate interpretation of these imaging findings.
Area of Science:
- Nuclear Medicine
- Oncologic Imaging
- Ophthalmology
Background:
- Positron Emission Tomography/Computed Tomography (FDG-PET/CT) is an advanced imaging technique.
- Choroidal melanoma is a type of eye cancer.
- Artificial eyes (ocular prostheses) are used to replace eyes lost to disease or trauma.
Observation:
- A case study involving a woman with a history of choroidal melanoma who underwent an FDG-PET/CT scan.
- An unexpected finding of focally increased radiotracer uptake was noted in her artificial eye.
Findings:
- The increased uptake in the ocular prosthesis on FDG-PET/CT can be misinterpreted without proper context.
- Knowledge of the specific prosthesis material and its implantation/replacement history is essential for accurate interpretation.
- FDG-PET/CT may offer a method to assess prosthesis vascularity, potentially replacing other imaging modalities.
Implications:
- This finding highlights the importance of correlating imaging results with patient history and prosthesis details.
- Accurate interpretation of FDG-PET/CT scans in patients with ocular prostheses is crucial to avoid misdiagnosis.
- FDG-PET/CT could be a valuable tool for monitoring ocular prosthesis health and vascularity.

Intracellular Signaling Affects Focal Adhesions
3.6K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Drugs Affecting Neurotransmitter Release or Uptake
1.6K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

Imaging Studies for Cardiovascular System V: CT
383
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...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
