MSK scans of the shoulder, ankle, forearm, and lower leg scans were completed on asymptomatic sample patients (n = 3).
Lately, I've noticed a surfeit of patients coming to my office (internal medicine) having undergone nonindicated screening exams that now "require" follow-up at regular intervals with further tests and scans (carotid scans, leg artery scans and so on).
On arrival, more blood was taken to test for D-dimers, and half the passengers had their legs scanned by ultrasound, which can detect the narrowing of blood vessels caused by thrombi.The results are controversial.
Each technique has drawbacks: a single proximal scan may miss a distal DVT, while whole-leg scanning can lead to distal DVT overtreatment.
In the leg, the scan parameters were TR/TM/TE = 2000/12/13 ms, and in the brain 2000/9.4/16 ms. Second-order shimming was used giving a full-width-half-maximum line width of approximately, 25 Hz in the calf muscle and 12 Hz in the head.
Both knees were scanned in 7 players and only dominant leg was scanned in 4 players due to limited parent consent.
Finally, it is possible that CTPA or V/Q imaging were considered unnecessary in some patients but still treated for presumed PE, i.e. positive bilateral leg DVT scans or echocardiography findings suggestive of PE.
For other treatment groups, only a single leg was scanned from each mouse.
The leg was scanned proximally and distally to ensure consistent identification of the sciatic nerve.
Neither the FDL nor the EDL muscle showed any hypointense signal indicating fibrosis on the lower leg MRI scans.
