PURPOSE To retrospectively determine whether blood oxygen level-dependent functional magnetic resonance (MR) imaging can aid prediction of postoperative memory changes in epileptic patients after temporal lobe surgery. MATERIALS AND METHODS This study was approved by the local ethics committee, and informed consent was obtained from all patients. Data were analyzed from 25 patients (12 women,...

Declaration of interest None. Auditory hallucinations occur frequently in people with psychiatric disorders, being most common in schizophrenia, and are often described as ‘voices’. Such hallucinations are usually treated with antipsychotic medication, but in 25–30% of patients they are refractory to traditional antipsychotic drugs. Their pathophysiological basis remains unknown, although funct...

Objective(s): In heart failure, the heart-to-mediastinum (H/M) ratio of the delayed image and washout rate (WR) are well-known as a powerful cardiac event predictors. H/M ratio quantifies the accumulation rate of MIBG in the myocardium and WR quantifies reduction of meta-iodobenzylguanidine (MIBG) accumulation in the heart from the early planar image to the delayed pla...

Over the last decade, imaging of myocardial viability has become a well-established indication in patients suffering from myocardial infarction. Myocardial viability imaging is routinely performed using (18)F-fluorodeoxyglucose positron emission tomography, single-photon emission computed tomography or magnetic resonance imaging. Only recently have several multi-slice spiral computed tomography...

STUDY DESIGN A prospective imaging study to develop diagnostic criteria. OBJECTIVE The aim of this study was to investigate image findings on delayed magnetic resonance imaging (MRI) after the acute phase of spinal cord injury without radiographic abnormality (SCIWORA) and their relationship with symptom severity. SUMMARY OF BACKGROUND DATA MRI is used to diagnose acute neurological injury,...

INTRODUCTION AND OBJECTIVES Computed tomography does not accurately determine which coronary lesions lead to myocardial ischemia and consequently further tests are required to evaluate ischemia induction. The aim of this study was to compare diagnostic accuracy between dual-energy computed tomography and magnetic resonance imaging in the assessment of myocardial perfusion and viability in patie...

To the Editor: Contrast-enhanced magnetic resonance imaging (CE-MRI) is an important imaging modality for the evaluation of isolated left ventricular noncompaction (LVNC). The delayed gadolinium enhancement has been identified in both compacted and noncompacted myocardium, and it may correlate with the clinical severity of LVNC (1–3). However, little is known about the histological basis of myo...

Use of magnetic resonance (MR) imaging for diagnosis of cardiac diseases and treatment monitoring is expanding. Delayed myocardial enhancement MR imaging is performed after administration of paramagnetic contrast agents and is used for a growing number of clinical applications. This technique was developed primarily for characterization of myocardial scarring after myocardial infarction. On del...

OBJECTIVE Since twenty-four-hour imaging by Tl-201 myocardial perfusion scintigraphy has been introduced as an effective additional procedure, the aim of this study was to compare this method's result with only rest redistribution procedure in the diagnosis of myocardial viability. METHODS Thirty patients (Seven female, 23 male; mean: 59.8 ± 10.7, 55.8-63.8 years old) with diagnosis of corona...
