While a superscan is relatively uncommon its recognition is important as it is associated with a number of important underlying diseases.
. 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. Whats a superscan It sounds like its in the bone marrow only. 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.
Skeletal scintigraphy commonly referred to as a bone scan BS is a valuable and versatile nuclear medicine tool. 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. An index of image quantitation related to the ratio of bone to soft tissue uptake is shown to be capable of clearly distinguishing these patients from patients in other categories.
In any normal bone scan one expects to see the kidneys and bladder secondary to normal renal excretion of. 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. 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.
A bone scan with diffused increased skeletal tracer uptake relative to soft tissue combined with faint renal activity is known as a superscan. Two years after the first. Bone scans myocardial perfusion studies MIBIstress tests thyroid uptake studies renal studies HIDA lymphoscintigraphy and sentinel node mapping VQ scans.
Nuclear Medicine eg. Learning points Super bone scan is a special condition of extremely high bone uptake relative to soft tissue with absent or faint renal. Disturbances in bone metabolism are more prevalent in Graves disease than in other types of hyperthyroidism.
It is usually accompanied by absent or faint renal activity Sy et al 1975. There were no significant differences regarding Ca AP and PTH between the Graves and non-Graves groups p 005. Intense osteoblastic activity in the bones causes diminished renal and background soft tissue uptake.
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. Patients underwent a routine whole-body bone study using the scanning technique. 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.
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. 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.
Ad Physicians See A Newly Approved PSMA PET Scan And How It Could Help Your APC Patients. 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. The superscan effect presents a technical challenge in the evaluation of lesions on bone scans in prostate cancer clinical trials.
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. 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. However a primary concern are false negatives associated with bone scans where diffuse metastasis is indistinguishable on superscans.
It says there were no suspicious focal bone mets. Diagnosis given that day were. Malignant neoplasm of.
Your doctor may order a bone scan if you have unexplained skeletal pain bone infection or a bone injury that cant be seen on a standard X-ray. 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. 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.
After a detailed literature search we did not find similar cases in. Superscan offers the following services to patients. A bone scan is a nuclear imaging test that helps diagnose and track several types of bone disease.
Metabolic superscan MSS was noted in 90 of the Graves cases 20 in TNG and in none of the AT group. Widespread bone metastases can occasionally give rise to a uniform distribution of 99Tcm methylene diphosphonate resulting in a superficially normal appearance on the bone scan. 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.
The addition of the bone. 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.
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. If secondary to metabolic bone disease uptake is more uniform and extends to the distal appendicular skeleton. Superscan Imaging Features Solitary or multiple foci of diffusely increased radiotracer uptake throughout the skeleton relative to soft tissue.
This is a report of bone scintigraphy demonstrating superimposed metastatic and metabolic superscan in a patient with prostate cancer who subsequently developed renal osteodystrophy. Will see diffuse or heterogeneouspatchy distribution within the axial skeleton. Visit The HCP Website To Learn About The Utility Of A PSMA Scan.
Whole-body images of the skeleton are obtained 3 hours after tracer administration. Technique A 20 mCi dose of 99m Tc-MDP is administered intravenously. 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.
Superscans on bone scintigraphy have been described mostly in metastatic and metabolic bone diseases with different patterns and appearances of radiotracer uptake.
