Superscan - can occur if metastases coalesce False Negative Bone Scan - osteolytic and osteoblastic components are balanced - multiple myeloma melanoma renal cell carcinoma 2.

. Submitted by Dr Rishu Sangal Consultant. A super scan in scintigraphy is defined as intense symmetric radiotracer activity in the bones increased bone. National Center for Biotechnology Information.

My understanding from UTSW is superscan is when mets are too diffuse to count and they extend throughout axial and into. Diffuse bone metastases and metabolic bone diseases are the differential diagnoses of a superscan. Primary malignant bone tumours Indication - detects metastasis - detects extent of lesion for resection skip lesions 3.

While the typical heterogeneous appearance of metastases normally is distinct from homogeneous uptake in metabolic bone disease the appearance of confluent disease a superscan can be quite similar as seen in the present patient 4-7. Diffuse increased uptake on bone scan. However a primary concern are false negatives associated with bone scans where diffuse metastasis is indistinguishable on.

Benign bone tumours Most show low grade uptake. This bone scan of a patient with metastatic disease demonstrates the superscan phenomenon. Nuclear Medicine eg.

Tracer uptake is so avid in bone that there is almost no renal excretion the kidneys are barely visualised. There were no significant differences regarding Ca AP and PTH between the Graves and non-Graves groups p 005. Superscan offers the following services to patients.

Every 89 weeks for the first 6 months then every 12 weeks. While a superscan is relatively uncommon its recognition is important as it is associated with a number of important underlying diseases. Malignant neoplasm of prostate secondary malignant neoplasm of bone marrow secondary malignant neoplasm of bone secondary malignant neoplasm of lymph nodes of multiple sites.

It is usually accompanied by absent or faint renal activity Sy et al 1975. Anterior and posterior images of a whole body bone scan of a 42-year-old male diagnosed at the age of 41 with adenocarcinoma of the prostate gland. Metabolic superscan MSS was noted in 90 of the Graves cases 20 in TNG and in none of the AT group.

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.

Die Skelettszintigrafie auch Knochenszintigrafie engl. 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. In todays modern healthcare system bone scans are relatively quick inexpensive and widely available.

A bone scan with diffused increased skeletal tracer uptake relative to soft tissue combined with faint renal activity is known as a superscan. This appearance has been associated with two main pathological groups. It may occur in widespread metastatic.

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. The bone scan images show skeletal involvement of the skull ribs spine and pelvis. Although a superscan can occur in a broad range of conditions both malignant and metabolic the vast majority are due to high volume bony.

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. He subsequently had a scrotal orchidectomy and received 30Gy of. Love et al 2003.

Super scan Semin Nucl Med. Bone scan is part of the staging modality commonly used to evaluate bone metastasis. Bone scan genannt ist ein nuklearmedizinisches bildgebendes Verfahren Szintigrafie das zum Nachweis von Knochen-Anteilen mit einem erhöhten Knochenstoffwechsel dient.

Assess soft tissue lung liver adrenal CNS lesions per RECIST 11. Example of images obtained on one scan with different CT weightings. This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy.

Two years after the first. Diagnosis given that day were. Bereiche mit einem erhöhten Knochenstoffwechsel Herde finden sich beispielsweise bei Knochenmetastasen im Rahmen.

The addition of the bone. Soft tissue uptake ratio. The first impression of the bone scan was a superscan especially because of the fact that the kidneys were not shown.

Diffuse increased uptake on bone scan. 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.

Disturbances in bone metabolism are more prevalent in Graves disease than in other types of hyperthyroidism. Monday June 04 2012 bone scan skeletal metastasis superscan. 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.
