bone scan superscan

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 scan is part of the staging modality commonly used to evaluate bone metastasis.

. NON-METASTATIC CASTRATE RESISTANT PROSTATE CANCER NMCRPC LYMPH NODES Perform lesion. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake. Metabolic superscan MSS was noted in 90 of the Graves cases 20 in TNG and in none of the AT group.

The appearance of bone scans following fractures including immediate and long-term studies. Assess soft tissue lung liver adrenal CNS lesions per RECIST 11. While a superscan is relatively uncommon its recognition is important as it is associated with a number of important underlying diseases.

BONE Imaging by CT andor MRI Include chest CT1 Include prostate MRI if necessary2 Imaging frequency. There were no significant differences regarding Ca AP and PTH between the Graves and non-Graves groups p 005. 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.

A super scan in scintigraphy is defined as intense symmetric radiotracer activity in the bones increased bone. This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy.

17 superscan Prostate Cancer CASE 17 Clinical Presentation A 72-year-old man with a history of metastatic prostate cancer is referred for a bone scan because of pain in the left shoulder and lower neck Fig. 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. 20 Coleman RE Mashiter G Whitaker KB Moss DW Rubens RD Fogelman I.

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. Diffuse bone metastases and metabolic bone diseases are the differential diagnoses of a superscan. Disturbances in bone metabolism are more prevalent in Graves disease than in other types of hyperthyroidism.

A skeletal superscan in patients with prostate cancer has been demonstrated in the literature with 18 F-choline PETCT 1 and 68 Ga-PSMA PETCT 2 imaging. It is usually accompanied by absent or faint renal activity Sy et al 1975.

Superscan offers the following services to patients. This appearance has been associated with two main pathological groups. Bone Scan with Confusing Appearance.

Every 89 weeks for the first 6 months then every 12 weeks. After a detailed literature search we did not find similar cases in the literature with 99m Tc-PSMA imaging. Superscan Phenomenon Monday June 04 2012 bone scan skeletal metastasis superscan This bone scan of a patient with metastatic disease demonstrates the superscan phenomenon.

Superscan - can occur if metastases coalesce False Negative Bone Scan - osteolytic and osteoblastic components are balanced - multiple myeloma melanoma renal cell carcinoma 2. It has the general appearance of a superscan. MRI Hart en long onderzoeken.

We present a patient with metastatic prostate cancer with known bone involvement and unknown osteomyelofibrosis. 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. Tracer uptake is so avid in bone that there is almost no renal excretion the kidneys are barely visualised.

However a primary concern are false negatives associated with bone scans. Bone scans myocardial perfusion studies MIBIstress tests thyroid uptake studies renal studies HIDA lymphoscintigraphy and sentinel node mapping VQ scans. Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake.

In todays modern healthcare system bone scans are relatively quick inexpensive and widely available. Love et al 2003. This scan demonstrates that in a patient with both affiliations metabolic bone disease can override even severe osseous metastases on a bone scan raising the suspicion of an overlying metabolic bone disorder.

A superscan is defined as a bone scan which demonstrates prominent uptake of bone radiotracer in the skeleton relative to soft tissue with absent or faint visualisation of the kidneys. A bone scan with diffused increased skeletal tracer uptake relative to soft tissue combined with faint renal activity is known as a superscan. Benign bone tumours Most show low grade uptake.
