Diagnostic performance of multishot echo-planar imaging (RESOLVE) and non-echo-planar imaging (HASTE) diffusion-weighted imaging in cholesteatoma with an emphasis on signal intensity ratio measurement.

Purpose: To evaluate the diagnostic efficacy of multishot echo-planar imaging (EPI) [RESOLVE (RS)] and non-EPI (HASTE) diffusion-weighted imaging (DWI) in detecting cholesteatoma (CHO), and to explore the role of signal intensity (SI) ratio measurements in addressing diagnostic challenges.

Methods: We analyzed RS-EPI and non-EPI DWI images from 154 patients who had undergone microscopic middle ear surgery, with pathological confirmation of their diagnoses. Two radiologists, referred to as Reader A and Reader B, independently reviewed the images without prior knowledge of the outcomes.

Comparison of epidural and intravenous route for acute and chronic postoperative pain control in patients with gynecological malignancy.

Objectives: This study compared the effects of patient-controlled epidural and intravenous analgesia on acute and chronic postoperative pain in patients who were operated on for gynecological malignancy.

Methods: Postoperatively, patient-controlled analgesia was administered via epidural route to Group 1 and the intravenous route to Group 2. Pain was evaluated using the Visual Analog Scale (VAS) in the acute phase at postoperative 24 hours and at 6 months in the chronic phase.

Effects of long term oral acrylamide administration on alpha naphthyl acetate esterase and acid phosphatase activities in the peripheral blood lymphocytes of rats.

Acrylamide is an important industrial chemical; it also is formed in starch-rich foodstuffs during baking, frying and roasting. Most acrylamide exposure occurs by ingestion of processed foods. We investigated possible immunotoxic effects of extended administration of low doses of acrylamide in rats.

An ioMRI-assisted case of cervical intramedullary diffuse glioma resection.

Purpose: To date, application of intraoperative magnetic resonance imaging (ioMRI) to enhance surgical quality for spinal intramedullary neoplastic lesions has been rarely reported. Moreover, in developing countries or regions, ioMRI accessibility remains very limited. This report describes a technology design of high-field ioMRI accessible for multioperation rooms via a case presentation of an imaging-assisted surgical excision of human cervical spinal cord diffuse glioma.
