Deviation of Latitude Cut: A Simple Sign to Differentiate Total Hip Arthroplasty from Hemiarthroplasty in Radiography.

This study aims to propose latitude cut deviation for differentiating hip arthroplasty types and evaluate its diagnostic utility in distinguishing total hip arthroplasty (THA) from hemiarthroplasty using radiography. After assessing various cup designs from top manufacturers for THA and hemiarthroplasty, we conducted a retrospective study on 40 patients (20 THA and 20 hemiarthroplasty). Three readers independently evaluated the radiographs, assessing acetabular sparing, cup-bone interface texture, and latitude cut deviation.

Lymphangiography and lymphatic embolisation for the treatment of chyle leaks after neck surgery: assessment of lymphangiography findings and embolisation techniques.

Objective: To assess lymphangiography findings and outcome of lymphatic embolisation to manage chyle leak after neck surgery.

Methods: Consecutive cases of lymphangiography performed between April 2018 and May 2022 for management of chyle leaks related to neck surgery were retrospectively reviewed. Lymphangiography findings, techniques, and outcomes were analysed.

Comparison of Virtual Unenhanced Images Derived From Dual-Energy CT With True Unenhanced Images in Evaluation of Gallstone Disease.

Objective: The aim of this study was to compare gallstones on virtual unenhanced images and true unenhanced images acquired with dual-energy CT (DECT).

Materials And Methods: We enrolled 112 patients with right upper quadrant pain and clinically suspected acute cholecystitis or gallstone who underwent DECT--including unenhanced, arterial, and portal phases. Eighty-three gallstones with composition proven by semiquantitative Fourier transform infrared spectroscopy from 45 patients who had undergone cholecystectomy (40 cholesterol gallstones from 21 patients, 43 calcium gallstones from 24 patients) were included.

Doppler ultrasonography measurement of hepatic hemodynamics during Valsalva maneuver: healthy volunteer study.

Purpose: The aim of our study was to assess the hemodynamic change of liver during the Valsalva maneuver using Doppler ultrasonography.

Methods: Thirty healthy men volunteers were enrolled (mean age, 25.5±3.

Clinical implications of T-wave inversion in an asymptomatic population undergoing annual medical screening (from the Korean Air Forces Electrocardiogram Screening).

This study aimed to determine prevalence, differentiate underlying causes, and identify the benign group in subjects with asymptomatic T-wave inversion (TWI). We retrospectively read 12-lead electrocardiograms from 3,929 consecutive asymptomatic men in the air force (3,929 participants, mean age 39.3 ± 8.

Dual energy CT in patients with acute abdomen; is it possible for virtual non-enhanced images to replace true non-enhanced images?

This study aims to determine whether virtual non-enhanced images derived from dual-energy computed tomography (CT) can replace true non-enhanced images in patients with acute abdomen. Patients with acute abdomen (n = 202) underwent multidetector CT including non-enhanced and contrast-enhanced images obtained at the portal phase using the dual-energy technique. CT attenuation values were measured in abdominal organs.

Lateral topography for reducing effective dose in low-dose chest CT.

Objective: The purposes of this study were to assess radiation exposure during low-dose chest CT by using lateral topography and to compare the lateral topographic findings with findings obtained with anteroposterior topography alone and anteroposterior and lateral topography combined.

Subjects And Methods: From November 2011 to February 2012, 210 male subjects were enrolled in the study. Age, weight, and height of the men were recorded.

iNOS promotes HBx-induced hepatocellular carcinoma via upregulation of JNK activation.

Inducible nitric oxide (iNOS) is closely correlated with chronic inflammation in hepatitis B virus X protein (HBx)-induced hepatocellular carcinoma (HCC). However, the molecular mechanisms through which iNOS contribute to hepatocarcinogenesis remain poorly understood. Therefore, we investigated the role of iNOS in signaling pathways underlying HBx-induced liver tumorigenesis.

Low-dose chest computed tomography as a screening tool: findings in 536 aircrews.

Background: Plain chest radiographs and pulmonary function tests have been used for pulmonary screening for flight duties of aircrews of the Republic of Korea Air Force. However, the screening accuracy of plain chest radiographs is controversial. Chest CT imaging with low-dose protocol (LDCT) improves detection of intra-thoracic abnormalities compared to plain chest radiographs.

Asymptomatic brain lesions in pilots: a comparative study with non-flying personnel using brain MRI.

Introduction: As modern aircraft fly at higher altitudes with rapid velocity, pilots have been put in the environment with a possible increasing risk of brain injury and could sustain cumulative brain damage. However, very few studies have investigated brain lesions using MRI in asymptomatic pilots. We evaluated asymptomatic pilots for the presence of cerebral lesions using MRI.

Transient sulcal hyperintensities on fluid-attenuated inversion recovery in migraine with aura: transient sulcal hyperintensities in migraine.

Migraine has been found to be associated with patent foramen ovale. However, in practice, it is difficult to show that microemboli via patent foramen ovale can induce a migraine attack. Our patient showed transient sulcal hyperintensities on fluid-attenuated inversion recovery images during a migraine attack.

Gd-EOB-DTPA enhanced micro-MR imaging of hepatic tumors in H-ras 12V transgenic mice.

Rationale And Objectives: The aims of this study were to evaluate the morphologic characteristics and growth pattern of hepatic tumors in H-ras 12V transgenic (TG) mice using a micro-magnetic resonance (MR) system and to assess the usefulness of gadolinium ethoxybenzyl diethylenetriamine penta-acetic acid (Gd-EOB-DTPA) enhancement for the detection of hepatic tumors in these mice.

Materials And Methods: Hepatocellular carcinoma lines were established to allow insertion of the H-ras 12V transgene under the control of the albumin enhancer/promoter. Seven H-ras 12V TG mice and four wild-type mice were included in this study.
