Benign bone tumours.

. The total counts acquired during the scan were used to compare the skeletal uptake of the radiopharmaceutical between prostate patients showing superscan image patterns n38 prostate cancer patients with normal scans n40 and a control group n40 with normal. Total of 6027 bone scans were examined in a 5-year period and out of which 80 cases were diagnosed as superscan. Patients underwent a routine whole-body bone study using the scanning technique.

While a superscan is relatively uncommon its recognition is important as it is associated with a number of important underlying diseases. The overall incidence of superscan in different type of cancers was 13 806027. Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake.

Diagnosis given that day were. Indication - detects metastasis - detects extent of lesion for resection skip lesions. It says there were no suspicious focal bone mets.

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. 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. 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.

Up to 10 cash back A skeletal superscan in patients with prostate cancer has been demonstrated in the literature with 18 F-choline PETCT and 68 Ga-PSMA PETCT imaging. Its cause is known with most conditions but in a few the mechanism is unclear. This appearance has been associated with two main pathological groups.

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. Head abdomen and pelvis chest angiogram including coronary thoracic cerebral renal abdominal limbs colonography cholangiogram dual energy imaging including gout and kidney stone scans intervention. The examination is most commonly performed using the radiotracer Technetium-99m Tc99m complexed to a diphosphonate either methylene diphosphonate MDP forming Tc99m-MDP or hydroxydiphosphonate HDP forming Tc99m.

This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy. This type of scan results in the. Whole-body images of the skeleton are obtained 3 hours after tracer administration.

Two years after the first. 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. 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.

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. 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. False Negative Bone Scan - osteolytic and osteoblastic components are balanced - multiple myeloma melanoma renal cell carcinoma.

Most show low. Scanning the whole skeleton helps in diagnosing a wide range of bone disorders including. Prostate cancer 4680 was the most common cause of superscan appearance followed by breast cancer 1080.

In any normal bone scan one expects to see the kidneys and bladder secondary to normal renal excretion of. 2 faint activity in the kidneys usually ascribed to rapid uptake in bone so that none reaches the kidneys 4 diffuse metastatic. Learning points Super bone scan is a special condition of extremely high bone uptake relative to soft tissue with absent or faint renal.

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. 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. It is usually accompanied by absent or faint renal activity Sy et al 1975.

A super scan refers to a unique pattern seen on a bone scan. Superscan is defined as a bone scan which demonstrates markedly increased skeletal radioisotope uptake relative to soft tissues in association with absent or faint renal activity absent kidney sign Superscan was first described by Osmond et al. Breast cardiac MRCP angiogram head spine shoulder elbow wrist hip knee and ankle.

Technique A 20 mCi dose of 99m Tc-MDP is administered intravenously. A bone scan might help determine the cause of unexplained bone pain. The test is sensitive to differences in bone metabolism which are highlighted in the body by the radioactive tracer.

Superscan - can occur if metastases coalesce. Primary malignant bone tumours. 1 diffuse symmetrical increase in bone uptake of the marker.

Apart from prostate cancer which is the most common condition associated with a superscan other malignancies like breast cancer lung cancer 1 2 3 4 can cause superscan appearance on. A super scan is well-known phenomenon which is characterized by a strikingly high bone to soft tissue ratio on skeletal scintigraphy with a uniform symmetrical increase in bone uptake and absent. Malignant neoplasm of.

After a detailed literature search we did not find similar cases in. A bone scan 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. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake.

Although a superscan can occur in a broad range of conditions both malignant and metabolic the vast majority are due to high volume bony metastatic disease. The superscan effect presents a technical challenge in the evaluation of lesions on bone scans in prostate cancer clinical trials. Skeletal scintigraphy commonly referred to as a bone scan BS is a valuable and versatile nuclear medicine tool.
