Hypertension crises and management during radiofrequency ablation of adrenal pheochromocytoma: A case report.

This case report describes the radiofrequency (RF) ablation of a pheochromocytoma in a 35-year-old female with multiple endocrine neoplasia (MEN) II syndrome, who previously underwent a right adrenalectomy and thyroidectomy. The patient presented with a new tumor in the left adrenal gland, detected via imaging, without evidence of metastasis. Opting against surgical adrenalectomy due to previous surgeries, she underwent RF ablation after preparatory alpha and beta blockader.

Fibrin sealants in lumbar annuloplasty after endoscopic discectomy as a method to prevent recurrent lumbar disc herniation.

Fibrin sealant as a promising agent for providing scaffold and efficient hemostasis is widely accepted in several specialties. However, the outcome of Fibrin sealants in lumbar annuloplasty after endoscopic discectomy has not been evaluated in patients with disc herniation. The goal of this study was to evaluate the efficacy, response, and probability of future recurrence rates in herniated nucleus pulposus (HNP) with the use of fibrin sealant in conjunction with endoscopic disc surgery.

New Policy and Regulations for a Radiology-Oncology Center During the COVID-19 Outbreak in Tehran, Iran.

On February 19, 2020, the first case of a patient infected with Coronavirus Disease-2019 (COVID-19) was announced in Iran. The number of infected patients increased rapidly, and all health care centers faced an extremely challenging situation in Iran. The centers had to adopt new regulations and approaches to keep their patients and staff safe while providing service to society.

Common CT Findings of Novel Coronavirus Disease 2019 (COVID-19): A Case Series.

Given the highly infectious nature of the coronavirus disease 2019 (COVID-19) virus and the lack of proven specific therapeutic drugs and licensed vaccines effective against it, early diagnosis of the disease is of paramount importance. The common chest CT imaging of confirmed COVID-19 cases is discussed here, which shows ground-glass opacity, crazy paving, and consolidation.

The Role of Emergency Radiology in COVID-19: From Preparedness to Diagnosis [Formula: see text].

Emergency trauma radiology, although a relatively new subspecialty of radiology, plays a critical role in both the diagnosis/triage of acutely ill patients, but even more important in providing leadership and taking the lead in the preparedness of imaging departments in dealing with novel highly infectious communicable diseases and mass casualties. This has become even more apparent in dealing with COVID-19, the disease caused by the novel coronavirus SARS-CoV-2, first emerged in late 2019. We review the symptoms, epidemiology, and testing for this disease.

Transarterial Bleomycin-Lipiodol Embolization (B/LE) for Symptomatic Giant Hepatic Hemangioma.

Background: Large hepatic hemangiomas can cause symptoms such as pain and bleeding. No consensus currently exists on the optimal management of large and symptomatic hemangiomas. The purpose of this study was to evaluate the role of transarterial bleomycin-lipiodol embolization (B/LE) in the treatment of symptomatic large hepatic hemangioma.

Repeated Intraportal Injection of Mesenchymal Stem Cells in Combination with Pioglitazone in Patients with Compensated Cirrhosis: A Clinical Report of Two Cases.

Background: Transplantation of mesenchymal stem cells (MSCs) in combination with pioglitazone, an agonist of peroxisome proliferator-activated receptor-γ (PPAR-γ), can reduce liver fibrosis in models of liver injury. In this study, we conducted a pilot study of intraportal infusion of autologous MSCs in combination with pioglitazone to assess safety, feasibility, and effectiveness in patients with compensated cirrhosis.

Methods: Two patients with compensated cirrhosis were enrolled in this study.

Intraportal Infusion of Bone Marrow Mononuclear or CD133+ Cells in Patients With Decompensated Cirrhosis: A Double-Blind Randomized Controlled Trial.

Liver-shape analysis and quantification is still an open research subject. Quantitative assessment of the liver is of clinical importance in various procedures such as diagnosis, treatment planning, and monitoring. Liver-shape classification is of clinical importance for corresponding intra-subject and inter-subject studies.

Three cuts method for identification of COPD.

Two main forms of COPD (Chronic Obstructive Pulmonary Disease) refer to a group of lung diseases that block airflow and cause a huge degree of human suffering. A new method for identifying and estimating the severity of COPD from three-dimensional (3-D) pulmonary X-ray CT images would be helpful for evaluation of treatment effects and early diagnosing is presented in this paper. This method has five main steps.

Data were obtained from the medical records of 156 thalassemia major patients in Tehran.

Complementary effect of H MRS in diagnosis of suprasellar tumors.

Objective: Suprasellar tumors are considered exceptionally important in neurosurgical practice due to their proximity to vital portions of the brain. Predicting histology of these tumors is of prime importance in determining the surgical approach, prognosis, and probable postoperative complications. There are numerous cases where computed tomography and magnetic resonance imaging (MRI) fail to predict histology.
