Article Synopsis
  • The study aims to examine changes in whole-brain gray matter volume (GMV) in HIV-negative patients with general paresis of the insane (GPI) using a method called voxel-based morphometry (VBM).
  • Eighteen GPI patients were compared to 24 healthy individuals, revealing significant decreases in GMV across multiple brain regions in the GPI group, alongside increases in areas like the basal ganglia and hippocampus.
  • Results indicated that specific GMV changes correlated negatively with cognitive test scores, suggesting that VBM could be a useful tool for diagnosing GPI based on brain structure.

Background: Chronic liver disease (CLD) will affect the enhancement of hepatic parenchyma and portal vein on abdominal-enhanced MRI.

Objective: To investigate the difference in liver parenchyma and portal vein enhancement in patients with CLD of different liver function grades between Gd- EOB-DTPA and Gd-DPTA in the portal venous phase (PVP).

Methods: This retrospective study included 218 patients with CLD who had undergone abdominal enhanced MRI from January 2019 to June 2020.

Background: Acute-on-chronic liver failure (ACLF) is a syndrome with high 28- and 90-day mortality rates. Magnetic resonance imaging (MRI) has been widely used to diagnose and evaluate liver disease. Our purpose is to determine the value of the imaging features derived from Gd-DTPA-enhanced MRI for predicting the poor outcome of patients with ACLF and develop a clinically practical radiological score.

Background: Establish a CT-based diagnostic radiomic model for AIDS complicated with pulmonary cryptococcosis and evaluate the diagnostic efficacy of this model.

Methods: This retrospective study enrolled 98 AIDS patients with pulmonary cryptococcosis and 103 AIDS patients with other infections or neoplastic lesions, comprising a total of 699 lesions. Patients were randomly divided into a training group and test group at a ratio of 2.

Background: To retrospectively analyze CT appearances and progression pattern of COVID-19 during hospitalization, and analyze imaging findings of follow-up on thin-section CT.

Methods: CT findings of 69 patients with COVID-19 were evaluated on initial CT, peak CT, and pre-discharge CT. CT pattern were divided into four types on CT progression.

To investigate the computed tomography (CT) imaging and pathological basis of the linear shadows connecting pulmonary segmental arteries to horizontal fissure (hereinafter referred to as "linear shadow") on thin-slice CT.Collect 127 clinical cases to analyze the display and morphology of linear shadows on the thin-slice CT and to measure their length, thickness, and angle. Collect 11 autopsy specimens of coal worker's pneumoconiosis to conduct an imaging and pathology basis control study for the linear shadows.

In total, 11 asymptomatic carriers who underwent nasal or oropharyngeal swab tests for SARS-CoV-2 after being in close contact with patients who developed symptomatic 2019 coronavirus disease (COVID-19) were enrolled in this study. The chest multidetector computed tomography (CT) images of the enrolled patients were qualitatively and quantitatively analyzed. The findings of the first chest CT were normal in 3 (27.

Purpose: We aimed to retrospectively analyze the imaging changes detected in the follow-up of coronavirus disease 2019 (COVID-19) patients on thin-section computed tomography (CT).

Methods: We included 54 patients diagnosed with COVID-19. The mean interval between the initial and follow-up CT scans was 7.

Rationale And Objectives: To retrospectively analyze the chest imaging findings in patients with coronavirus disease 2019 (COVID-19) on thin-section CT.

Materials And Methods: Fifty-three patients with confirmed COVID-19 infection underwent thin-section CT examination. Two chest radiologists independently evaluated the imaging in terms of distribution, ground-glass opacity (GGO), consolidation, air bronchogram, stripe, enlarged mediastinal lymph node, and pleural effusion.

Rationale: Kaposi's sarcoma (KS) is the most common malignant tumor in HIV-infected people and occurs mainly in the skin, mucous membranes, and lymph nodes. Approximately 33% of the initial skin manifestations of AIDS and approximately 35% to 79% of KS occur during disease progression. Otherwise, AIDS-related facial KS that was simultaneously examined by magnetic resonance imaging (MRI) is rare.

Objective: To retrospectively analyse the imaging findings of the linear shadows that connect the oblique fissures and the costal pleurae on the superior segments of the lower lobes on thin-slice lung CT.

Materials And Methods: Thin-slice CT scans of 221 cases of normal lungs and 86 abnormal lungs were collected. The parameters of the imaging observations included the existence of the superior segmental linear shadow, its morphology, length, and starting position, bird-beak sign, and adjacent structures on the pleural end.

Objectives: To retrospectively evaluate short linear shadows connecting pulmonary segmental arteries to oblique fissures in thin-section CT images and determine their anatomical basis.

Methods: CT scanning was performed on 108 patients and 11 lung specimens with no lung diseases around the oblique fissures or hila. Two radiologists evaluated the imaging.

Purpose: We aimed to perform an imaging analysis of interlobar fissures and their variations using thin-section computed tomography (CT).

Methods: Volumetric thin-section CT scanning was performed in 208 subjects. Interlobar fissures were observed on axial images, and reconstructed coronal and sagittal images were observed by multiplanar reformatting (MPR).

Article Synopsis
  • A 17-year-old girl visited the ER with severe abdominal pain, nausea, vomiting, and melena; endoscopy revealed a large, 15 cm polyp in her duodenum.
  • After surgical removal of the polyp, the patient remained healthy at a 5-year follow-up, highlighting the importance of excising giant gastric adenomas due to their cancer risk and the need for monitoring for early signs of gastric neoplasm. *

Background: Computed tomographic pulmonary angiography (CTPA) has been established as a first-line test in the acute pulmonary embolism (APE) diagnostic algorithm, but the assessment of the severity of APE by this method remains to be explored.

Purpose: To retrospectively evaluate right ventricular (RV) dysfunction and severity in patients with APE without underlying cardiopulmonary disease using helical computed tomography (CT).

Material And Methods: Seventy-three patients (35 men and 38 women) were divided into two groups according to the clinical findings: severe APE (n=22) and non-severe APE (n=51).
