bone scan superscan

There were no significant differences regarding Ca AP and PTH between the Graves and non-Graves groups p 005. Superscan - can occur if metastases coalesce.

Primary malignant bone tumours.

. 3D volume rendered images of the heart in a CT Coronary Angiogram study. May represent occult malignancy such breast cancer malignant pleural effusion soft tissue sarcoma or metastatic disease in the liver Identification of the presence of kidneys on every bone scan. The Superscan Philosophy Bulk Billing All Referrals Accepted.

It is usually accompanied by absent or faint renal activity Sy et al 1975. Superscan is home to the worlds most advanced CT Scanner the Siemens Force. Diffuse bone metastases and metabolic bone diseases are the differential diagnoses of a superscan.

After a detailed literature search we did not find similar cases in the literature with 99m Tc-PSMA imaging. A bone scan with diffused increased skeletal tracer uptake relative to soft tissue combined with faint renal activity is known as a superscan. 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.

X-Ray OPG DEXA Example of images obtained on one scan with different CT weightings. Materials and Methods. 171 Technique A 20 mCi dose of 99m Tc-MDP is administered intravenously.

Bone scintigraphy 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. Soft tissue uptake ratio. The aim of the study was to analyze overall incidence and the causes of superscan on Tc99m MDP whole body bone scan in a 5-year 3 2 retrospective and prospective study manner in patients with established diagnosis of malignancy and to find out relationship between the superscan and other parameters such as age sex duration of.

In the 5-year study period we evaluated whole body bone scans of 6027 patient with underlying malignancy out of which 80 patients were reported as superscans and overall incidence of superscan appearance in different type of cancer patients was 13 Sixty-three 787 were men and 17 212 were women The mean age of the patients was 584 14 years SD and. 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. 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.

However a primary concern are false negatives associated with bone scans where diffuse metastasis is. Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake. If the kidneys are not seen a superscan should be suspected.

Prostate cancer is the most common malignancy associated with superscan along with others such as lung cancer breast cancer and haematological malignancies. False Negative Bone Scan - osteolytic and osteoblastic components are balanced - multiple myeloma melanoma renal cell carcinoma. The CT uses only 10 of the radiation dose of other CT Scanners and is the most accurate machine to non-invasively diagnose Coronary Artery Disease.

In todays modern healthcare system bone scans are relatively quick inexpensive and widely available. We have established a simple set of objective reference bands to complement visual interpretation of the scan. Love et al 2003.

So CT from same day says diffuse sclerosis in bones also multiple sclerotic lesions in the vertebral bodies and most in keeping with metastatic disease. Bone scan is part of the staging modality commonly used to evaluate bone metastasis. This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy.

Whats a superscan It sounds like its in the bone marrow only. 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. Metabolic superscan MSS was noted in 90 of the Graves cases 20 in TNG and in none of the AT group.

Bone scans myocardial perfusion studies MIBIstress tests thyroid uptake studies renal studies HIDA lymphoscintigraphy and sentinel node mapping VQ scans. It says there were no suspicious focal bone mets. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake.

Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake. 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. This appearance has been associated with two main pathological groups.

1 About 4060 of the injected Tc-99m MDP is excreted in the urine. Indication - detects metastasis - detects extent of lesion for resection skip lesions. Most show low.

Joekaty in reply to Tall_Allen 3 years ago. Super bone scan is a special condition of extremely high bone uptake relative to soft tissue with absent renal radioactivity visualisation absent kidney sign. 2 Therefore significant renal and bladder radioactivity are normal in most scans.

Nuclear Medicine eg. 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. 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 super scan in scintigraphy is defined as intense symmetric radiotracer activity in the bones increased bone. While a superscan is relatively uncommon its recognition is important as it is associated with a number of important underlying diseases. 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.

Detection of incidental soft tissue uptake. Benign bone tumours. Disturbances in bone metabolism are more prevalent in Graves disease than in other types of hyperthyroidism.

Quantitation using total counts recorded directly from the whole-body bone scan showed a significantly raised value in the superscan group only P. A fifth of a second can save your life.
