Pneumothorax after percutaneous CT-guided lung nodule biopsy: a prospective, multicenter study.

Background: Pneumothorax is a common complication induced by computed tomography (CT)-guided percutaneous needle biopsy, with a frequency of 17-40.4%. It remains debatable how to predict and prevent the occurrence of post-biopsy pneumothorax.

Iodine-125 brachytherapy for a desmoid tumor in the abdomen-thorax: A retrospective study.

Purpose: To investigate the safety and efficacy of iodine-125 seed implantation in the treatment of abdomen-thorax desmoid tumors (DTs).

Methods And Materials: Data from 14 DT patients who received brachytherapy with iodine-125 seeds were retrospectively collected from 2014 to 2020. The operation was completed using CT guidance and the treatment plan system (TPS).

A cohort autopsy study defines COVID-19 systemic pathogenesis.

Severe COVID-19 disease caused by SARS-CoV-2 is frequently accompanied by dysfunction of the lungs and extrapulmonary organs. However, the organotropism of SARS-CoV-2 and the port of virus entry for systemic dissemination remain largely unknown. We profiled 26 COVID-19 autopsy cases from four cohorts in Wuhan, China, and determined the systemic distribution of SARS-CoV-2.

Clinical efficacy of computed tomography-guided iodine-125 seed implantation therapy for patients with metastatic epidural spinal cord compression: A retrospective study.

Background: This study evaluated the clinical efficacy of computed tomography (CT)-guided radioactive iodine-125 ( I) seed implantation in patients with metastatic epidural spinal cord compression (MESCC).

Materials And Methods: A cohort of 22 patients with MESCC were retrospectively enrolled. All patients underwent CT-guided I seed implantation therapy via standard procedures.

Efficacy and safety of computed tomography-guided I brachytherapy for lymph node metastatic from hepatocellular carcinoma.

Purpose: A survival benefit may be associated with the positive control of extrahepatic lymph node metastasis (LNM) of hepatocellular carcinoma (HCC). However, no standard treatment exists. The aim of this study was to evaluate the safety and efficacy of iodine-125 (I) brachytherapy (BT) of LNM of HCC, especially in patients with multiple lymph nodules or repeated lymph node recurrence.

Assessment of the cancer risk factors of solitary pulmonary nodules.

There are no large samples or exact prediction models for assessing the cancer risk factors of solitary pulmonary nodules (SPNs) in the Chinese population. We retrospectively analyzed the clinical and imaging data of patients with SPNs who underwent computer tomography guided needle biopsy in our hospital from Jan 1st of 2011 to March 30th of 2016. These patients were divided into a development data set and a validation data set.

Treatment of portal vein tumor thrombus using ¹²5Iodine seed implantation brachytherapy.

We reported two cases of liver metastasis with portal vein tumor thrombus that developed after liver transplantation for hepatocellular carcinoma (HCC). Both the patients were women aged 43 and 55 years, who had liver metastasis and portal vein tumor thrombus formation after liver transplantations for HCC. For the treatment of portal vein tumor thrombus, (125)I seeds were implanted into the hepatic tissue under the guidance of preoperative computed tomography (CT) images with a total radiation dose of 130 Gy.

Whole-body diffusion-weighted imaging vs. FDG-PET for the detection of non-small-cell lung cancer. How do they measure up?

Objective: To compare the diagnostic efficacy of whole-body diffusion-weighted imaging (WB-DWI) and [18F] fluoro-2-D-glucose PET/CT(FDG-PET/CT)for assessment of non-small cell lung cancer (NSCLC) patients.

Materials And Methods: A group of 56 patients (21 female, 35 male; 35-76 years) with NSCLC proved by pathologic examination or follow-up imaging findings was set as reference standards, and all patients underwent both WB-DWI at 1.5T (MAGNETOM Avanto) and PET/CT (Biograph 16).

[CT guided radioactive seed (125)I implantation in treating multiple bone metastasis].

Objective: To investigate the clinical value of CT guided radioactive seed (125)I implantation in treating bone metastasis.

Methods: 28 multiple bone metastatic tumor patients with 116 metastatic lesions totally, adenocarcinoma of lung in 6 cases, squamous cell carcinoma of lung, renal clear-cell carcinoma, and carcinoma of prostate in 4 cases each, hepatocellular carcinoma and colon carcinoma in 3 cases each, breast carcinoma in 2 cases, and malignant schwannoma and pancreatic cancer in 1 case each, 13 males and 15 females, aged 49.8, underwent CT guided radioactive seed (125)I implantation into bone metastatic lesions.

[The feasibility and safety of radiofrequency ablation for secondary splenomegaly and hypersplenism in dogs].

Objective: To assess the feasibility and safety of radiofrequency ablation (RFA) in spleen to treat secondary splenomegaly and hypersplenism in dogs.

Methods: Fourteen healthy mongrel dogs were randomly divided into two groups: group A (n = 4) and group B (n = 10) Both groups underwent ligation of the splenic vein and its collateral branches to induce congestive splenomegaly. At the end of the 3rd week, radiofrequency thermal ablation of the spleen was performed in the group B via laparotomy.

Tuberculosis of pancreas and peripancreatic lymph nodes in immunocompetent patients: experience from China.

Aim: To determine the clinical, radiographic and laboratory characteristics, diagnostic methods, and therapeutic variables in immunocompetent patients with tuberculosis (TB) of the pancreas and peripancreatic lymph nodes.

Methods: The records of 16 patients (6 male, 10 female; mean age 37 years, range 18-56 years) with tuberculosis of the pancreas and peripancreatic lymph nodes from 1983 to 2001 in the Southwest Hospital were analyzed retrospectively. In addition, 58 similar cases published in Chinese literature were reviewed and summarized.

Experimental study on the feasibility and safety of radiofrequency ablation for secondary splenomagely and hypersplenism.

Aim: To assess the feasibility and safety of radiofrequency ablation (RFA) in treatment of secondary splenomagely and hypersplenism.

Methods: Sixteen healthy mongrel dogs were randomly divided into two groups, group I (n=4) and group II (n=12). Congestive splenomegaly was induced by ligation of splenic vein and its collateral branches in both groups.
