Predicting Healthy C5 Spinal Nerve Stumps Eligible for Grafting with MRI, Tinel Test, and Rhomboid Electromyography: A Retrospective Study of 295 Consecutive Brachial Plexus Surgeries.

Background MRI, Tinel test, and rhomboid electromyography (EMG) can be used to predict whether C5 spinal nerve stumps are healthy and eligible for grafting in acute adult brachial plexus injuries, but their comparative diagnostic efficacies have not been evaluated. Purpose To compare diagnostic performances of MRI, Tinel test, and rhomboid EMG in predicting healthy C5 spinal nerve stumps that are eligible for grafting. Materials and Methods This retrospective study included consecutive adult patients with acute brachial plexus injury who underwent microreconstructions between January 2008 and December 2018.

Imaging Approaches for Accurate Determination of the Quadriceps Angle.

Objectives: A retrospective study was conducted using magnetic resonance image (MRI) and a full-length standing scanogram (FLSS) to measure the quadriceps angle (Q-angle) while avoiding soft tissue interference.

Methods: Two steps were retrospectively carried out in two case series. The first step involved using MRI to define the standardized patellar center (PC) and the tibial tubercle (TT) on the frontal plane of the MRI in one group of 60 consecutive patients (from July 2016 to December 2016, 29 men and 31 women, average of 46 years).

Value of homodyned K distribution in ultrasound parametric imaging of hepatic steatosis: An animal study.

Ultrasound is the first-line tool for screening hepatic steatosis. Statistical distributions can be used to model the backscattered signals for liver characterization. The Nakagami distribution is the most frequently adopted model; however, the homodyned K (HK) distribution has received attention due to its link to physical meaning and improved parameter estimation through X- and U-statistics (termed "XU").

Varied influence of the femoral or tibial component on quadriceps angles: Verified by imaging studies.

Objective: The aim of this study was to evaluate the varied influence of femoral or tibial component on Quadriceps angles (Q-angle) measured with magnetic resonance image (MRI) and full-length standing scanogram (FLSS) techniques.

Methods: Two groups of patients were studied. The first group underwent MRI studies and the second group underwent FLSS studies.

Transarterial embolization for postpartum hemorrhage: lessons learned.

Background: Although transarterial embolization (TAE) can powerfully control postpartum hemorrhage (PPH), clinical failure of TAE is not uncommon.

Purpose: To discover whether any parameters could predict timely clinical failure of TAE, then whether a supplementary intervention could be promptly initiated.

Material And Methods: We retrospectively analyzed 118 TAE procedures in 113 patients with PPH performed at our institution between January 2012 and May 2015.

Diagnostic performance of dual-energy contrast-enhanced subtracted mammography in dense breasts compared to mammography alone: interobserver blind-reading analysis.

Purpose: To analyse the accuracy of dual-energy contrast-enhanced spectral mammography in dense breasts in comparison with contrast-enhanced subtracted mammography (CESM) and conventional mammography (Mx).

Materials And Methods: CESM cases of dense breasts with histological proof were evaluated in the present study. Four radiologists with varying experience in mammography interpretation blindly read Mx first, followed by CESM.

Comparison of ultrasonographically guided fine-needle aspiration and core needle biopsy in the diagnosis of parotid masses.

Background: To retrospectively compare the accuracies of ultrasound-guided fine-needle aspiration (USFNA) and ultrasound-guided core needle biopsy (USCNB) in the diagnosis of parotid masses.

Methods: A total of 171 patients (aged 17-86 years, mean 54 years) with parotid masses (35 malignant and 136 benign lesions) underwent either USFNA (n = 107) or USCNB (n = 64). The diagnostic accuracies for differentiating benign from malignant lesions of both examinations were compared.

CT-guided hook wire localization of subpleural lung lesions for video-assisted thoracoscopic surgery (VATS).

Background/purpose: Histologic diagnosis of suspicious small subpleural lung lesions is difficult and often impossible using existing image-guided needle biopsy techniques including video-assisted thoracoscopic wedge resection. Preoperative lung lesion localization provides a more obvious target to facilitate intraoperative resection. This study reviewed the indications, results and complications of CT-guided hook wire localization for subpleural lung lesions in video-assisted thoracoscopic surgery (VATS).

Video-assisted thoracoscopic surgery for catamenial hemoptysis: the rationale of preoperative computed tomography-guided hook-wire localization.

Catamenial hemoptysis is a rare disease. Hormone ablation therapy is the treatment of choice with multiple side effects. We report a case of pulmonary endometriosis with deep and changeable focus.

Risk factors of pneumothorax and bleeding: multivariate analysis of 660 CT-guided coaxial cutting needle lung biopsies.

Background: The results of studies identifying the risk factors for pneumothorax and bleeding in CT-guided coaxial lung needle biopsies were inconsistent and some were even contradictory. All reported series were small with patient populations averaging about 200.

Study Objectives: To determine the risk factors for pneumothorax and bleeding after CT-guided coaxial cutting needle biopsy of lung lesions.

Primary adenocarcinoma arising in esophageal colon interposition: report of a case.

Colon interposition has become a favored technique for esophageal reconstruction. We report a 79-year-old man with primary adenocarcinoma arising in the interposed colon 30 years after esophageal reconstruction for esophageal cancer. The occurrence of a carcinoma in a colon removed from its natural location and serving a different function suggests this rise in incidence may result from the action of carcinogens on colonic cells over an increasing period.

Uterine artery embolization for symptomatic uterine leiomyoma and adenomyosis.

Background And Purpose: Uterine artery embolization (UAE) is increasingly accepted as an alternative treatment for symptomatic uterine leiomyoma and adenomyosis. The purpose of this study was to compare the outcomes of UAE in 3 diagnostic categories--submucosal leiomyoma, intramural leiomyoma, and adenomyosis--to assist in patient selection for this relative new form of therapy.

Methods: The medical records of 43 patients (aged 22 to 54 years) who underwent UAE for symptomatic uterine leiomyoma or adenomyosis were retrospectively reviewed.

Left internal jugular vein thrombosis due to a lung tumor.

Deep vein thrombosis is a common disease among Caucasians but is rare in Asia. Venous thrombosis may be fatal, for example by a pulmonary embolism and right or left atrial thrombosis. Alternatively, deep vein thrombosis may follow a benign pattern such as femoral and popliteal vein thrombosis.

The use of ultrasonography in preoperative localization of digital glomus tumors.

Small glomus tumors of the digits of the hand are difficult to excise and may be associated with relatively high rates of recurrence. This study was designed to prospectively evaluate the utility of preoperative ultrasound localization of such tumors to facilitate removal and to reduce recurrence rates. During a 5-year period, 34 patients clinically diagnosed with glomus tumors involving their digits were examined with high-resolution ultrasonography (5 to 9 MHz).

US-guided catheter drainage of postoperative head and neck fluid collections.

Purpose: To analyze results of percutaneous catheter drainage of large fluid collections in the head and neck region noted in the immediate postoperative period.

Materials And Methods: Thirty-four consecutive patients with 41 large fluid collections in the head and neck detected 7-10 days after oncologic surgery underwent percutaneous catheter drainage. There were 29 men and five women, with a mean age of 52.

Factors affecting diagnostic accuracy of CT-guided coaxial cutting needle lung biopsy: retrospective analysis of 631 procedures.

Purpose: To analyze variables affecting diagnostic accuracy of computed tomography (CT)-guided percutaneous coaxial cutting needle biopsy of lung lesions.

Materials And Methods: A retrospective analysis of factors affecting diagnostic accuracy of CT-guided percutaneous coaxial cutting needle lung biopsy was performed in 631 consecutive procedures with confirmed final diagnoses. Benign and malignant needle biopsy results were cross-examined with correct and incorrect final outcomes to determine diagnostic accuracy.

Sonographically guided antegrade common femoral artery access.

Objective: To evaluate the feasibility of sonographically guided antegrade common femoral artery puncture and superficial femoral artery access.

Methods: Fifty antegrade common femoral artery punctures and superficial femoral artery access procedures were performed under sonographic guidance alone in 30 consecutive patients (24 male and 6 female; mean age, 55.1 +/- 25.

Sonographic evaluation of mammographically detected microcalcifications without a mass prior to stereotactic core needle biopsy.

Purpose: The purpose of this prospective study was to evaluate the clinical usefulness of sonographically re-evaluating areas of microcalcification found mammographically before undertaking stereotactic core needle biopsy (SCNB).

Methods: Patients with nonpalpable breast lesions appearing as microcalcifications on mammograms and who had been referred to us for SCNB were re-evaluated sonographically before the procedure. None of the breast lesions had been associated with a density on the mammograms, and the initial sonographic evaluations had been negative.
