Hide Abstract
Focal increased lower thoracic spinal cord (18)F FDG uptake is not infrequently observed as a normal physiological finding and may be confused for spinal cord metastases. This study was conducted to evaluate a possible correlation between the lower thoracic (T11-T12) spinal uptake and lower limb movements/ambulatory status of the patients as a surrogate. The primary endpoint was to identify the possible cause(s) of the normal variant focal increased thoracic spinal cord (T11-T12) (18)F FDG activity and correlate it with the lower limb movements/ambulatory status of the patients. This was a retrospective analysis of PET-CT scans of 200 patients with solid and hematological malignancies. The focal relatively increased (18)F FDG activity in the lower thoracic spinal cord correlated strongly with the (18)F FDG intensity of the liver, bowel, C3-C5 cervical cord activity, weight of the patient and injected dose of (18)F FDG. With regard to the primary endpoint, no significant correlation was found between the ambulatory status of patients in any of the groups and thoracic spine SUVmax. This could be further assessed by performing dual studies in the same patient with and without moderate to excessive leg motion. Identifying this variant focal increased (18)F FDG activity can minimize errors of misdiagnosis and unnecessary further investigation.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
