Somatostatin receptor (SSTR) PET has demonstrated a significant improvement over conventional imaging (CI) in patients with neuroendocrine tumors (NETs). SSTR should replace 111In-pentetreotide scintigraphy (OctreoScan; Mallinckrodt) all indications which the latter is currently being used
Prostate-specific membrane antigen (PSMA) is expressed by the majority of clinically significant prostate adenocarcinomas, and patients with target-positive disease can easily be identified PSMA PET imaging. Promising results PSMA-targeted radiopharmaceutical therapy have already been obtained in early-phase studies using various combinations targeting molecules radiolabels. Definitive evidence safety efficacy [177Lu]Lu-PSMA-617 combination standard-of-care has demonstrated metastatic...
Omphalocele is a congenital abdominal wall defect with herniation of viscera into sac. Tc-99m DMSA renal cortical scan functional imaging technique used for detecting parenchymal defects, mostly in patients recurrent urinary tract infection as well abnormalities. Renal anomalies are known to accompany omphalocele. In this retrospective study, we present case cephalad ectopia observed on scintigraphy patient omphalocele due large hernia sac containing most the liver; and review abnormalities...
The objective of this study was to determine the patient-specific optimal time surgery preoperatively improve operative success in gamma probe-guided parathyroid localization. Fifteen patients with hyperparathyroidism underwent a double-phase Tc99m-MIBI (15-20 mCi) scintigraphy clearance kinetics from and thyroid glands point at which target-to-background ratio achieved. Optimal determined on basis maximal. On day received same dose were taken operating room ratio. A four-gland exploration...
The pathophysiological relation between periodic lateralized epileptiform discharges (PLEDs) and epileptic seizures is not known the exact causative mechanism of PLEDs still remains unclear. In this report, authors present a case in which EEG displayed after complex partial seizure. This patient, with long history seizures, had previously undergone right standard anterior temporal lobectomy hippocampectomy, diagnosis mesial sclerosis. She one seizure 72 days operation was admitted to...
Positron emission tomography (PET) is a diagnostic imaging technique that has progressed rapidly from being research in laboratories to routine clinical modality. The most widely used radiotracer PET Fluorine18-fluorodeoxyglucose (F18-FDG), which an analogue of glucose. FDG uptake cells directly proportional glucose metabolism cells. Since increased many fold malignant tumors high sensitivity and negative predictive value. with now the standard care initial staging, monitoring response...
To evaluate the agreement of multichannel intraluminal impedance-pH monitoring (MII-pHM) and gastroesophageal reflux scintigraphy (GES) for diagnosis disease.Seventy-five consecutive patients with suspected disease (GERD) underwent 24-h combined MII-pHM recording one hour radionuclide during course study. Catheters 6 impedance channels 1 pH sensor were placed transnasally. Impedance data analysis performed automatically manually. For monitoring, was defined as a retrograde 50% drop in...
<h3>Objective:</h3> The aim of this study was to identify the immune response in sentinel lymph nodes (SLNs) patients with endometrial and cervical cancers by analyzing number S-100-, CD1a-, CD83-positive (+) dendritic cells that are major antigen-presenting cells. <h3>Methods:</h3> A total 56 early-stage cancer (n = 32, cervical; n 24, cancer) underwent SLN biopsy. Sentinel non-SLNs were stained antibodies against S-100, CD1a, CD83 as markers for find out whether SLNs immunomodulated...
The Diagnostic Efficiency of 99m Tc-EDDA
Objectives This study has been conducted to investigate the non-invasive diagnostic journey of patients with a transthyretin amyloid cardiomyopathy (aTTR-CM) in Turkey, identify challenges and uncertainties encountered on path diagnosis from perspectives expert physicians, develop recommendations that can be applied such cases. Methods employed three-round modified Delphi method included 10 cardiologists five nuclear medicine specialists. Two hematologists also shared their opinions survey...
Extramedullary myelomatous disease is an aggressive condition where clonal plasma cells proliferate outside the bone marrow, allowing independent survival. This state generally associated with negative outcomes. A 65-year-old woman presented progressive bilateral hypochondrial pain, was initially misattributed to inflammatory etiology, and consequently managed corticosteroid therapy. marrow biopsy offered after further deterioration confirming cell myeloma. Afterward, 18 F-FDG PET/CT...
The purpose of this study was to assess the reliability and validity modified Conconi test on Concept II rowing ergometers. Twenty-eight oarsmen conducted 3 performance tests separate days. Reliability assessed using break point in heart rate (HR) linearity called (CT) retest (CRT) for noninvasive measurement anaerobic threshold (AT). Blood lactate considered gold standard assessment AT, CT by blood samples taken during an incremental load (ILT) According results, mean power output (PO)...
OBJECTIVE In this study we hypothesized that if timing of gamma probe‐guided parathyroidectomy were individualized according to an optimal‐time‐to‐surgery technique, in vivo characterization parathyroid lesions would be possible. We compared our findings with ex counting method (“20% rule”) and frozen section results. STUDY DESIGN AND SETTINGS Thirty‐five patients who referred for surgical treatment hyperparathyroidism studied. Maximum thyroid sestamibi uptake ratio (UR max ) was measured by...
In this study, bone response, possible use and ultimate fate of a chemically-synthesized poly(L-lactide)-hydroxyapatite (PLLA-HA) composite was experimented in canine mandible. Bilateral mandibular second premolars were extracted four dogs. The PLLA-HA placed into left surgical sites, right extraction sites used as controls. After three months healing, specimens harvested from each animal processed for histological evaluation. Bone uptake methylene diphosphonate (99mTc-MDP) calculated...
