superscan bone scan
In todays modern healthcare system bone scans are relatively quick inexpensive and widely available. In bone imaging the term superscan has been used to describe the appearance of high skeletal uptake of radionuclide combined with low background activity Osmond etal 1975.

Qualitative comparison showed patterns of avid bone uptake with diminished visualization of kidney and bladder activity in the superscan group and normal scans in the control and prostate patient groups.
. 1 diffuse symmetrical increase in bone uptake of the marker. A superscan is defined as a bone scan which demonstrates markedly increased skeletal radioisotope uptake relative to soft tissues in association with absent or faint genito-urinary tract activity. Intense osteoblastic activity in the bones causes diminished renal and background soft t.
We presented a 61-year-old mans surprising Tc-MDP whole-body blood pool superscan pattern with early unexpected generalized bone uptake. Tc-99m V DMSA shows increased bone uptake in patients having a superscan appearance in metastatic or metabolic bone disease. This appearance has been associated with two main pathological groups.
A bone scan in which there is excessive skeletal radioisotope uptake in relation to soft tissues along with absent or faint activity in the genitourinary tract is known as a superscan Apart from prostate cancer which is the most common condition associated with a superscan other malignancies like breast cancer lung cancer1234 can cause superscan. Superscan Bone scintigraphy Diffuse bone metastasis 99mTc- HMDP Marrow infiltration Corresponding Author. Rapid COVID-19 Testing Available Now.
A superscan is an imaging appearance on a Tc-99m diphosphonate bone scan which occurs as a result of a high ratio of bone to soft tissue tracer accumulation. In bone imaging the term superscan has been used to describe the appearance of high skeletal uptake of radionuclide combined with low background activity Osmond etal 1975. Quantitation using total counts recorded directly from the whole-body bone scan showed a significantly raised value in the superscan.
Superscan is a state of the art radiology and nuclear medicine group which offers patients the best technology in CT Nuclear Medicine X-Ray Ultrasound and Bone Mineral Densitometry. Superscan provides patients with highest quality pictures at the lowest possible radiation dose and is also home to the worlds lowest radiation dose and. A superscan is a pattern described as abnormal bone scan indicating extensive bony metastases associated with various neoplastic diseases.
3405 NW Federal Hwy 1. A Sub-superscan is a term used for scan findings in which the up-take is atypical of a superscan but the patient has extensive bone metastases as presented in our case report. Could be misinterpreted as a normal bone scan.
Offices conveniently located in Martin County Okeechobee County and Highlands County. A super scan refers to a unique pattern seen on a bone scan. A Superscan is described as a beautiful bone scan.
2 faint activity in the kidneys usually ascribed to rapid uptake in bone so that none reaches the kidneys 4 diffuse metastatic. Superscan PredictionAnother Benefit of Early Renal Views in Bone Scans. As a malignancy workup in a patient without obvious suspicious origin a whole-body Tc.
Journal of Nuclear Medicine April 1985 26 4 428-429. A superscan is an imaging appearance on a Tc-99m diphosphonate bone scan which occurs as a result of a high ratio of bone to soft tissue tracer accumulation. Bone scans from 407 patients with nasopharyngeal carcinoma were reviewed retrospectively.
The scans are recognizable by the high ratio of bone to soft tissue activity the absence of focal lesions in the axial skeleton and there are usually no renal images.

This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy.
Test results within 15 minutes. Its cause is known with most conditions but in a few the mechanism is unclear. Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake.
Love et al 2003. Journal of Nuclear. A superscan is defined as bone scan planar imaging with diffuse increased skeletal tracer uptake relative to soft tissue combined with diminished or non-existent renal activity Brenner et al 2012.
This is a PDF-only article. Only six superscans 15 were found. It may occur in widespread metastatic.
Tc-99m V DMSA imaging may play a role in the evaluation of patients with equivocal bone scan findings for a superscan. In a superscan the uptake of Tc-Methelene Diphosphonate MDP is prominent in the skeleton relative to soft tissue with absent or faint visualisation of the kidneys. A superscan is a term given to the appearances on a nuclear bone scan when bony uptake of Tc99m disphosponate is so profound that the usual physiological uptake observed in the kidneys is no longer apparent.
Rapid COVID-19 Testing and Anti-Body Testing. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake. He complained of weakness and undesired weight loss with anemia and elevated erythrocyte sedimentation rate.
Superscan PredictionAnother Benefit of Early Renal Views in Bone Scans. Widespread bone metastases can occasionally give rise to a uniform distribution of 99Tcm methylene diphosphonate resulting in a superficially normal appearance on the bone scan. It is usually accompanied by absent or faint renal activity Sy et al 1975.
Although a superscan can occur in a broad range of conditions both malignant and metabolic the vast majority are due to high volume.
