Reliability of postoperative MR imaging in the determination of level and side of lumbar spinal decompression surgery.

We examined factors that may have influenced the reliability, including demographics, type of surgical decompression, use of a drain, and time interval from surgery to MRI. RESULTS: Significantly fewer levels were correctly determined by the resident (77/86 cases, 89.5%) compared with the radiologist (84/86 cases, 97.7%) (P = 0.014). The resident interpreted significantly more MR images incorrectly in cases where a drain was used (n = 8; P

In this study, we constructed a PEG-MnO2-OPN siRNA nanocomplex via a modular streptavidin bridge for the theranostic treatment of renal carcinoma in vitro and in vivo. This strategy of utilizing PEG-MnO2 nanosheets for OPN siRNA delivery showed effective tumor growth inhibition of 786-O tumor-bearing mice, and such a process could be monitored by the activated T1-weight MRI, illustrating the promising potential of PEG-MnO2 nanosheets for the fabrication of an MRI-based theranostic system.

This article reviews a clinical case in which MRD testing, both in bone marrow and in functional imaging, is part of the standard of care. It also reviews the different modalities of MRD testing and current practice guidelines. Finally, patients with myeloma may be tested for MRD after treatment because this is part of the routine response assessment according to International Myeloma Working Group criteria and correlates with clinical outcomes. Important questions such as when to stop therapy for sustained MRD-negative patients or whether to change treatments for patients who go from MRD negative to positive without other...

Objective The aim of this study was to assess the signal intensity of the anterior pituitary (AP) gland on unenhanced T1-weighted images in patients with history of serial intravenous injections of gadodiamide and normal renal function. Materials and Methods We included 53 patients who had undergone at least 5 injections of gadodiamide and a control group of 15 subjects who underwent at least 5 brain magnetic resonance imaging without gadolinium-based contrast agents. Using unenhanced sagittal T1-weighted images, values of mean signal intensity of the AP and of the central pons were obtained. Anterior pituitary–...

Conclusions The detection of significant amounts of Gd in RBCs and WBCs indicates that GBCAs can cross blood cell membranes. This finding may play a role in our understanding of the processes that are at the basis of Gd retention in the tissues of patients who have received the administration of GBCAs.

Objectives The aim of this study was to evaluate the significance of a new imaging sign, the “cloverleaf sign,” in diagnosing deep infiltrating endometriosis (DIE) with magnetic resonance imaging (MRI) in concordance to intraoperative findings. Materials and Methods This retrospective study included 103 patients operated during the January 2016 to June 2018 period with preoperative 1.5 T and 3 T MRI, with or without vaginal and rectal gel filling. Magnetic resonance imaging scans were read blinded to intraoperative findings by a specialized gynecologic radiologist and a junior radiologist, and then compare...

This study examines whether cortical thickness and surface area differ between children with left-hemisphere focal epilepsy (LHE) and age-matched typically developing (TD) peers. We examined whether age differentially moderated cortical thickness between groups and if cortical thickness was associated with duration of epilepsy, seizure frequency, or neuropsychological functioning.MethodsThirty-five children with LHE and 35 TD children completed neuropsychological testing and 3T MR imaging. Neuropsychological measures included general intelligence and executive functioning. All MRIs were normal. Surface-based morphometric p...
