Metabolic superscan MSS was noted in 90 of the Graves cases 20 in TNG and in none of the AT group.

. Love et al 2003. BONE Imaging by CT andor MRI Include chest CT1 Include prostate MRI if necessary2 Imaging frequency. There is however no significant renal or soft tissue activity.

Assess soft tissue lung liver adrenal CNS lesions per RECIST 11. 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.

Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake. A super bone scan may result from a widespread. National Center for Biotechnology Information.

Disturbances in bone metabolism are more prevalent in Graves disease than in other types of hyperthyroidism. There were no significant differences regarding Ca AP and PTH between the Graves and non-Graves groups p 005. Bone scan is more sensitive in detecting metastases from prostate breast and lung cancer which are predominantly osteoblastic.

After a detailed literature search we did not find similar cases in the literature with 99m Tc-PSMA imaging. This patient had a known history of prostate cancer with an elevated PSA of 45 ngmL. Prostate cancer 4680 was the most common cause of superscan appearance followed by breast cancer 1080.

This appearance has been associated with two main pathological groups. In todays modern healthcare system bone scans are relatively quick inexpensive and widely available. Breast cardiac MRCP.

The scans are recognizable by the high ratio of bone to soft tissue activity. 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. Every 89 weeks for the first 6 months then every 12 weeks.

The overall incidence of superscan in different type of cancers was 13 806027. Cerebral renal abdominal limbs colonography cholangiogram dual energy imaging including gout and kidney stone scans intervention. Nuclear Medicine eg.

Bone scintigraphy plays an important role in the early detection of bone metastases in patients with nasopharyngeal carcinoma and serial scans may aid the clinician to assess the therapeutic response. 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. The follow up bone scan shows uniform increased density of the axial and proximal appendicular skeleton resulting in excellent bone detail.

Total of 6027 bone scans were examined in a 5-year period and out of which 80 cases were diagnosed as superscan. Superscan offers the following services to patients. The findings are in keeping with multiple osteoblastic metastasis.

A superscan is a pattern described as abnormal bone scan indicating extensive bony metastases asso. Super bone scan is a special condition of extremely high bone uptake relative to soft tissue with absent renal radioactivity visualisation absent kidney sign1 About 4060 of the injected Tc-99m MDP is excreted in the urine2 Therefore significant renal and bladder radioactivity are normal in most scans. The previously seen multiple discrete lesions are no longer appreciable.

Bone scans myocardial perfusion studies MIBIstress tests thyroid uptake. However while a superscan should have greater uptake in the axial skeleton compared to the appendicular skeleton this scan is reverse raising the suspicion of an overlying metabolic bone. The appearance of the bone scan is consistent with a metabolic superscan in this case due to secondary hyperparathyroidism renal osteodystrophy.

It is usually accompanied by absent or faint renal activity Sy et al 1975. Authors A R Constable R W Cranage. Soft tissue uptake ratio.

The pattern of diffuse increased skeletal uptake with no tracer seen in the kidneysbladder is called a superscan. 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. Note that activity is increased throughout the entire skeleton including the distal appendicular skeleton which is characteristic of a superscan due to metabolic disorders.

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. While a superscan is relatively uncommon its recognition is important as it is associated with a number of important underlying diseases. Recognition of the superscan in prostatic bone scintigraphy Br J Radiol.

This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy. It is less sensitive in. The pattern of diffuse increased skeletal uptake with no tracer seen in the kidneysbladder is called a superscan.
