Validation of daily 0.35 T diffusion-weighted MRI for MRI-guided glioblastoma radiotherapy.

Background: MRI-Linac systems enable daily diffusion-weighed imaging (DWI) MRI scans for assessing glioblastoma tumor changes with radiotherapy treatment.

Purpose: Our study assessed the image quality of echoplanar imaging (EPI)-DWI scans compared with turbo spin echo (TSE)-DWI scans at 0.35 Tesla (T) and compared the apparent diffusion coefficient (ADC) values and distortion of EPI-DWI on 0.

Evolving concepts in margin strategies and adaptive radiotherapy for glioblastoma: A new future is on the horizon.

Chemoradiotherapy is the standard treatment after maximal safe resection for glioblastoma (GBM). Despite advances in molecular profiling, surgical techniques, and neuro-imaging, there have been no major breakthroughs in radiotherapy (RT) volumes in decades. Although the majority of recurrences occur within the original gross tumor volume (GTV), treatment of a clinical target volume (CTV) ranging from 1.

[Informativeness of whole-body diffusion-weighted magnetic resonance imaging and positron emission tomography with computed tomography in follicular lymphoma].

Aim: This study conducted the possibilities of diffusion-weighted magnetic resonance imaging of the whole body diffusion WB-MRI (in comparison with positron emission tomography with computed tomography PET/CT) in assessing the volume and prevalence of the tumor, as well as determining bone marrow (BM) damage (for various cytological types) in the diagnosis and staging of the disease in patients with FL.

Materials And Methods: A prospective comparative search study included 15 patients (4 men and 11 women, with a median age of 53 years) with newly diagnosed FL. Patients have not received antitumor chemotherapy previously.

[Pancreatic kallikrein, a protector of small intestine damage in post-ischemic toxemia].

The morphofunctional state of the small intestine was studied on a tourniquet shock model. The development of postischemic toxemia is followed by disorders of microcirculation leading to irreversible changes in the small intestine. The processes are associated with an increase of the proteolytic activity of the intestinal contents.

[Effect of cholecystokinin and bombesin on the neuronal impulse activity of the ventromedial hypothalamic nucleus].

I.v. administration of the C-terminal sulfated cholecystokinin octapeptide as well as microapplication of its analogues to the eye sclera induced an increase of firing rate in over 1/3 neurons of the ventromedial nucleus.
