BACKGROUND Carmustine (BCNU) wafer (Gliadel(®) Wafer) implantation after tumor resection is an approved treatment for high-grade glioma (HGG). These wafers change various characteristics on early postoperative magnetic resonance imaging (ep-MRI) including slight expansion of high-intensity areas on T2-weighted imaging (ep-T2-HIAs) into adjacent parenchyma without restricted diffusivity. We asse...

UNLABELLED Various methodologies for (99m)Tc-sestamibi parathyroid scintigraphy are in clinical use. There are few direct comparisons between the different methods and even less evidence supporting the superiority of one over another. Some reports suggest that SPECT is superior to planar imaging. The addition of CT to SPECT may further improve parathyroid adenoma localization. The purpose of ou...

The purpose of this study was to evaluate the diagnostic potential of dual time-point 18F-FDG PET/CT imaging with multiple metabolic parameters in malignancy-suspected bone/joint lesions. Fifty seven consecutive patients were recruited. PET parameters including SUVmax, SUVmean, metabolic tumor volume (MTV), total lesional glycolysis (TLG) and retention indexes (RIs) were obtained. Thirty five m...

Delayed contrast-enhanced inversion recovery (IR) gradient-echo MR imaging has been applied to several cardiac diseases, including myocarditis, sarcoidosis, hypertrophic cardiomyopathy, and myocardial damages induced by medical procedures. Although a preliminary study has indicated the usefulness of this imaging for the detection of right ventricular (RV) myocardial damage associated with arrhy...

Herein reported is the case of a young woman who had hyperinsulinaemic hypoglycaemia which was biochemically consistent with an insulinoma. Initial imaging was negative and definitive treatment was delayed until repeat imaging localized the tumour several years later. This case demonstrates the importance of clinical judgment and biochemical testing in the diagnosis of insulinoma despite negati...

Spinal cord neoplasms are rare lesions in children. Most of the spinal cord neoplasms are astrocytomas. Frequently the clinical symptoms are non-specific. Back pain is often the leading symptom. Diagnosis is often delayed. Magnetic resonance imaging is the imaging modality of choice. Preoperative brain and spine imaging covering the entire spine is mandatory to exclude cerebrospinal fluid seeding.

Introduction: Myocardial viability assessment is crucial in prognostic stratification and therapeutic decision making for patients after acute myocardial infarction. MRI has shown high capability in viability assessment, also compared to current clinical tools. Purpose: To define contrast enhanced (CE) MRI role in functional recovery prediction after acute myocardial infarction. Methods: 43 con...

Purpose: To analyze 68 Ga-PSMA-617 PET/CT or PET/MR and delayed images in patients diagnosed with suspicion of prostate cancer, to explore the optimal use for initial diagnosis staging cancer. Methods: Images from conventional scan by Ga-PSMA whole-body followed pelvic were retrospectively analyzed. Prostatic uptake was measured as SUVmax1 (conventional 1 h post injection) SUVmax2 (delayed 3 in...
