Unilateral Bleomycin-induced Interstitial Pneumonitis Mouse Model With Both a Healthy and a Diseased Lung.

Background/aim: A standard mouse model of pulmonary fibrosis has been created by intratracheal or intraperitoneal administration of bleomycin. However, a difficulty presented by this traditional method is its high mortality rate of more than 50% after bleomycin administration. In this study, we aimed to establish a unilateral lung disease model and to assess its feasibility and usefulness.

Pancreatic volume change using three dimensional-computed tomography volumetry and its relationships with diabetes on long-term follow-up in autoimmune pancreatitis.

Background: Several studies found that early pancreatic atrophy detected by computed tomography (CT) within 6 months was associated with a high incidence of diabetes in patients with type-1 autoimmune pancreatitis (AIP) receiving steroid therapy; however, no long-term follow-up studies have been performed.

Aim: To investigate pancreatic volume (PV) changes using three dimensional (3D)-CT volumetry and their relationship with IgG4 and diabetes in patients with AIP.

Methods: This retrospective study included 33 patients with type-1 AIP receiving steroid therapy.

Computed Tomography-guided Puncture: Preprocedural Preparation, Technical Tips, and Radioprotection.

Computed tomography-guided puncture is a useful technique for various interventional radiology procedures. Puncture from various locations and angles becomes possible using this technique. Moreover, bone and air do not interfere with the computed tomography image.

Analysis of Chromosome Test Results of 24,175 Miscarried Fetuses in Japan from 2000 to 2021.

Background: Fetal chromosome abnormalities, the most common cause of spontaneous abortion, were investigated pre-1980s. In recent years, chromosome testing has been outsourced to testing companies in Japan, and there have been few epidemiological studies of chromosome testing of miscarried fetuses on a nationwide scale.

Methods: We analyzed the chromosome test data of SRL Inc.

Radiofrequency Ablation in Patients with Interstitial Lung Disease and Lung Neoplasm: A Retrospective Multicenter Study.

Purpose: To retrospectively investigate the safety and effectiveness of percutaneous radiofrequency (RF) ablation by analyzing results in patients with lung neoplasm accompanied by interstitial lung disease (ILD) on computed tomography (CT) in a multicenter study.

Materials And Methods: Patients with lung neoplasm accompanied by ILD who underwent RF ablation between April 2002 and October 2017 at 7 institutions were investigated. Technical success rate and local tumor progression (LTP) of ablated tumors were evaluated.
