Nuclear medicine utilizes radiopharmaceuticals for visualizing the body's physiological processes and detecting disease severity. The associated instrumentation includes imaging and non-imaging apparatus, each vital in ensuring diagnostic accuracy and efficiency. Therefore, it is necessary to conduct a semi-br...
Thus, whole-body imaging is necessary only if a lesion cannot be found in the adrenal glands. [18F]FDG PET and [18F]FDOPA PET/CT together with MRI can help in preoperative mapping of PHEOs within both adrenal glands and guide surgeons toward the most appropriate (feasible) approach....
Also commonly called a bone scan, this is an imaging test specific to the skeleton. It may be used to look for fractures not easily visible on an x-ray, to help diagnose the cause of bone pain, to look for infections in the bone (called osteomyelitis), and to look for spread of can...
The LMNA gene is expressed in differentiated cells, whereas at least one LMNB gene is expressed in every somatic cell in the body.40,41 Lamins were found to be phosphorylated at serine and tyrosine residues during interphase and mitosis.42,43,44,45,46 In most cases, phosphorylation of lamins...
The scans can be performed at 12-15 cm/min (or faster) as the purpose of the scan is simply to determine the whole-body total counts rather than to produce a diagnostic image. Some investigators have taken issue with this concept holding that it is necessary to confirm tumor uptake before...
Bone scanning is useful for detecting tumors, which generally have high metabolic activity. Treatment in Nuclear Medicine In nuclear medicine imaging tests, injected radioactive substances do not harm the body. The radioisotopes used in nuclear medicine decay quickly, in minutes to hours, have ...
due to the changes in active bone marrow during childhood development. Therefore, careful consideration of radiationinduced myelosuppression is essential during protocol optimization for pediatric patients receiving radiotherapy outside the pelvic region. Keywords: Target delineation; Pediatric oncology patients;...
Child abuse:Non-accidental injury in babies and children is a challenging clinical conundrum. Diagnosis is crucial, and a high suspicion should always be maintained. Bone scan offers a high sensitivity exam that adds value as an adjunct to the traditional skeletal survey.[121][122][123][124][...
Chronic dyspnea in a 71-year-old woman. A 71-year-old woman with a history of WHO grade 3 obesity (body-mass-index 40.1 kg/m2) and type 2 diabetes was referred for worsening dyspnea (NYHA grade II-III). Clinically no other signs of congestion or fluid retention were observed. The ECG...
Dual-phase parathyroid scan [99mTc]Tc-MIBI scintigraphy is performed at two time points, i.e., at 10–15 min and 90–150 min after intravenous administration of the radiopharmaceutical. The administered activity ranges from approximately 400 to 900 MBq, depending on the patient’s body mass, ...
