UNLABELLED The brain distribution of 99mTc-ECD versus 123I-IMP was compared in patients with subacute stroke in order to compare diagnostic accuracy. METHODS A total of 25 patients with subacute stroke underwent early and delayed SPECT imaging with 99mTc-ECD and 123I-IMP. Washout of 99mTc-ECD was calculated and a differential percentage of activity (DPA)(More)
PURPOSE The influence of patient posture on the incidence and severity of gastroesophageal reflux is well known. Scintigraphic imaging, however, is routinely performed with the patient lying in the supine position, because current gamma camera designs do not allow for changes to the angle of the patient table. METHODS To overcome this difficulty and to(More)
UNLABELLED In vitro studies have demonstrated that (99m)Tc-methoxyisobutylisonitrile ((99m)Tc-MIBI) is a transport substrate of multidrug resistance (MDR)-related proteins. The aim of this clinical study was to evaluate whether (99m)Tc-MIBI scintigraphy was a functional imaging tool for in vivo detection of multidrug resistance-associated protein (MRP)(More)
The authors describe a complex regional pain syndrome (CRPS) and discuss its type according to the presence or absence of nerve injury. A patient underwent thromboendarterectomy of the right popliteal artery. Subsequently, right lower limb reflex sympathetic dystrophy developed, which was confirmed by scintigraphy and responded well to calcitonin treatment.(More)
AIMS To study the clinical hand findings in Behçet's disease (BD) and to observe scintigraphic changes of these areas. METHODS Fifty-seven randomly selected BD patients and the patients in the control group (N=40) were evaluated by two blind rheumatologists. The hands were examined for the presence of pain, tenderness, swelling, effusion, erythema,(More)
Focal hyperaemia is a fairly common phenomenon in the subacute phase of an ischaemic stroke. This has rarely been reported with iodine-123 iodoamphetamine (IMP) and has never been identified using technetium-99m bicisate (99mTc-ECD). In this report, we present the case of a patient suffering from a left cerebral posterior stroke. 123I-IMP single-photon(More)
UNLABELLED The purpose of the study was to evaluate the performance of dual-head coincidence gamma camera imaging using FDG in association with serum marker assays in identifying lung carcinoma in patients with abnormal findings on chest radiography. METHODS A prospective evaluation of FDG imaging with coincidence detection emission tomography (CDET)(More)
Two hundred and thirty-one patients underwent dual-isotope myocardial imaging (rest thallium-201 followed by stress technetium-99m sestamibi). The feasibility of the procedure was excellent: camera scheduling flexibility was improved and the duration of the procedure was less than that of a classical stress-redistribution procedure. Interpretation of(More)
OBJECTIVES The aim of the study was to evaluate the role of F-fluorodeoxyglucose ((18)F-FDG) PET/computed tomography (CT) in the early postoperative staging of breast cancer and to document (18)F-FDG PET/CT-based stage alterations and any subsequent impact on management. MATERIALS AND METHODS Between January 2009 and June 2012, PET/CT images of patients(More)
