bone scan superscan

A superscan is a bone scan which exhibits diffuse skeletal uptake of the radiopharmaceutical agent with little to no uptake within soft tissue including the kidneys and bladder. Although a superscan can occur in a broad range of conditions both malignant and metabolic the vast majority are due to high volume bony.

Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake.

. It is usually accompanied by absent or faint renal activity Sy et al 1975. The appearance of a superscan is frequently accompanied by an abnormal titer of serological markers IgG-VCA. National Center for Biotechnology Information.

These superscans can occasionally be misinterpreted as normal. Die Skelettszintigrafie auch Knochenszintigrafie engl. This type of scan results in the.

Superscan provides patients with highest quality pictures at the lowest possible radiation dose and is also home to the worlds lowest radiation dose and most advanced CT scanner the. Metabolic superscan MSS was noted in 90 of the Graves cases 20 in TNG and in none of the AT group. Bone scan genannt ist ein nuklearmedizinisches bildgebendes Verfahren Szintigrafie das zum Nachweis von Knochen-Anteilen mit einem erhöhten Knochenstoffwechsel dient.

Only six superscans 15 were found. 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. His Tc-99m PSMA images revealed diffuse bone infiltration in a pattern mimicking a bone scan.

Total of 6027 bone scans were examined in a 5-year period and out of which 80 cases were diagnosed as superscan. This appearance has been associated with two main pathological groups. The first impression of the bone scan was a superscan especially because of the fact that the kidneys were not shown.

Bone scans from 407 patients with nasopharyngeal carcinoma were reviewed retrospectively. Patients who were diagnosed as having superscan in the preceding 3 years with confirmed histopathological diagnosis were included in the retrospective group. It may occur in widespread metastatic.

Quantitation using total counts recorded directly from the whole-body bone scan showed a significantly raised value in the superscan group only P. 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. A superscan is a pattern described as abnormal bone scan indicating extensive bony metastases associated with various neoplastic diseases.

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. Note that activity is increased throughout the entire skeleton including the distal appendicular skeleton which is characteristic of a superscan due to metabolic disorders. 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.

There were no significant differences regarding Ca AP and PTH between the Graves and non-Graves groups p 005. This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy. In the prospective group all the patients who were reported to have superscan appearance over the.

In the normal patient both the osseous components of the skeletal system as well as the kidneys and bladder are visualized. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake. The previously seen multiple discrete lesions are no longer appreciable.

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. Love et al 2003. The findings are in keeping with multiple osteoblastic metastasis.

Records of all previous bone scans and reported patients of superscan were re-evaluated retrospectively. Gleason score was 54 and PSA at diagnosis was 419 μgl. Disturbances in bone metabolism are more prevalent in Graves disease than in other types of hyperthyroidism.

In todays modern healthcare system bone scans are relatively quick inexpensive and widely available. An index of image quantitation related to the ratio of bone to soft tissue uptake is shown to be capable of. 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.

The superscan effect presents a technical challenge in the evaluation of lesions on bone scans in prostate cancer clinical trials. 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. The follow up bone scan shows uniform increased density of the axial and proximal appendicular skeleton resulting in excellent bone detail.

The bone scan images show skeletal. The appearance of the bone scan is consistent with a metabolic superscan in this case due to secondary hyperparathyroidism renal osteodystrophy. Bereiche mit einem erhöhten Knochenstoffwechsel Herde finden sich beispielsweise bei Knochenmetastasen.

The overall incidence of superscan in different type of cancers was 13 806027. A superscan is defined as a bone scan which demonstrates markedly. There is however no significant renal or soft tissue activity.

Whole-body bone scintigraphy bone scan using a 99m Tc-labelled pharmaceutical is one of the most commonly performed radionuclide examinations. We have established a. 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.
