“…The fusion of DWI and HRCT images has been reported in previous studies [8][9][10][11][12] in which cholesteatoma lesions with high signal intensity on DWI were superimposed on the corresponding HRCT temporal bone structures to improve preoperative cholesteatoma detection, assessment, and localization; however, DWI and HRCT are 2 different imaging techniques, and the fusion process is cumbersome. Kanoto et al 13 and Watanabe et al 14 showed that DWI with MR cisternography can increase the accuracy of anatomic localization. However, MR cisternography sequences of the ear require additional scanning time, which may cause motion artifacts due to patient discomfort from the prolonged body position, leading to image-quality degradation.…”

“…Patients with a subjective score of ,3 for both fused images were excluded from further localization diagnosis. In this study, 4 anatomic regions of the middle ear (attic, tympanic cavity, mastoid antrum, and mastoid cavity) were used for localization as proposed by Kanoto et al: 13 1) attic: superior to the horizontal semicircular canal and anterior to the posterior margin of the horizontal semicircular canal; 2) the tympanic cavity: inferior to the horizontal semicircular canal and anterior to the posterior margin of the horizontal semicircular canal; 3) the mastoid antrum: superior to the horizontal semicircular canal and posterior to the posterior border of the horizontal semicircular canal; and 4) mastoid cells: inferior to the horizontal semicircular canal and posterior to the posterior border of the horizontal semicircular canal.…”

BACKGROUND AND PURPOSE: Cholesteatoma is an aggressive disease that may lead to hearing impairment. This study aimed to compare the utility of high-resolution CT and TSE-DWI fusion images with that of T2WI and TSE-DWI fusion images in the localization of middle ear cholesteatoma. MATERIALS AND METHODS:Seventy-one patients with middle ear cholesteatoma were retrospectively recruited. High-resolution CT, T2WI with fat suppression, and TSE-DWI scans were obtained, and image fusion was performed using a 3D reconstruction postprocessing workstation to form CT-DWI and T2WI-DWI fusion images. The quality of the 2 fused images was subjectively evaluated using a 5-point Likert scale with the horizontal semicircular canal transverse position as the reference. Receiver operating characteristic analysis was performed, and the diagnostic efficacies of CT-DWI and T2WI-DWI fusion images in localizing middle ear cholesteatoma were calculated.

“…DWI may also replace delayed gadolinium-enhanced T1w sequences [60]. Images from non-EPI sequences or newer EPI techniques such as RESOLVE can even be fused with anatomical images (T1w and T2w) in coronal and/or axial orientation to better localize suspected lesions [63,64]. This also helps to differentiate e. g. the characteristic T1 hyperintensity of cholesterol granuloma, or asymmetric apex fat, and opacified/infected petrous apex [65].…”

ZUSAMMENFASSUNGHintergrund Magnetic resonance imaging (MRI) ist ein essentielles bildgebendes Verfahren für die Beurteilung von Kopf-Hals Erkrankungen. Die diagnostische Aussagekraft der MRI ist jedoch stark von der entsprechenden Auswahl und Interpretation der Protokolle und Sequenzen abhängig. Das Ziel dieses Beitrags ist es, State-of-the-art-Sequenzen für die klinische Routine der Kopf-Hals-MRI zusammenzufassen und die Evidenz zu beschreiben, für welche medizinische Fragestellungen diese Sequenzen nützlich sind.Methode Literaturübersicht von State-of-the-art-Sequences in der Kopf-Hals-MRI.

“…Doctors often construct preoperative health education for patients and apply recovery technology in the perioperative period to reduce the operative stress response and enhance the postoperative recover treatment effect. 5,6 Research on FTS was first carried out in cardiac surgery in Europe and America. At present, the FTS concept has been successfully applied for treating colorectal cancer, esophageal cancer, stomach cancer, and thyroid surgery.…”

Objectives This study aimed to examine application of fast-track surgery (FTS) in the perioperative period of laparoscopic partial nephrectomy for renal tumors, and to discuss its effects and safety. Methods Eighty patients who received laparoscopic partial nephrectomy in urinary surgery from January 2016 to December 2017 were selected and randomly classified as the observation group (n = 40) and control group (n = 40). Traditional treatments were performed in the control group, while FTS was applied in the observation group. The complication rate after the operation was recorded. Results The duration of the operation and intraoperative blood loss were not different between the groups. The duration of anesthesia and fluid transfusion volume on the day of the operation were significantly less in the observation group than in the control group. The rates of infection of the incisional wound, nausea and vomiting, and anastomotic stomal bleeding were not significantly different between the groups. However, the rates of postoperative urinary tract infection, abdominal distension, thirst, hypothermia, and pulmonary infection were significantly lower in the observation group than in the control group. Conclusion Application of FTS in laparoscopic partial nephrectomy contributes to postoperative recovery and reduction of postoperative complications.
