In Spain, lung cancer (LC) is the fourth most common cancer. Managing LC involves different professionals, and cooperative and coordinated work is crucial. Therefore, important decisions are better made by Multidisciplinary Thoracic Tumour Boards (MTTBs).

Progressive pulmonary fibrosis (PPF) can be fatal in non-idiopathic interstitial lung diseases. We report a descriptive series of 13 patients with PPF who received treatment with nintedanib, a multitargeted tyrosine kinase inhibitor with antifibrotic effect. Although the reduced number of patients and the observational nature of a case series prevent us from providing strong evidence, our results suggest that nintedanib could be effective in PPF of various etiologies.

Background: To analyse if performing unenhanced CT of the liver aids in the evaluation of metastatic lesions, response assessment or alter the size of the lesions, compared with portal phase alone, in patients with hepatic metastases from breast carcinoma.

Patients And Methods: One-hundred and fifty-three CT scans of 36 women were included. Scans consisted of unenhanced, arterial and portal delayed phases of the liver.

Article Synopsis
  • The study aimed to compare early and delayed phases of contrast-enhanced thoracic CT for assessing pleural lesions in patients with malignant pleural effusions.
  • Six observers reviewed CT images from 36 patients, scoring the quality of visualization of pleural thickening or nodules and indicating which phase image they preferred.
  • Results showed that the delayed phase had significantly higher mean attenuation of pleural lesions and was preferred by the observers in 77.8% to 91.7% of cases, indicating it is more effective for evaluating pleural findings.

Objective: The purpose of this study was to evaluate the superiority of either of two protocols for combined contrast-enhanced thoracic and abdominal CT of patients with lung cancer by comparing contrast enhancement, contrast-related artifacts, image quality, and radiation dose.

Subjects And Methods: In this randomized controlled crossover clinical trial, 77 patients who underwent 203 CT examinations were enrolled. All patients underwent at least two examinations performed with both protocols.

In the last 2 decades, endoscopic endonasal transsphenoidal surgery has become the most popular choice of neurosurgeons and otolaryngologists to treat lesions of the skull base, with minimal invasiveness, lower incidence of complications, and lower morbidity and mortality rates compared with traditional approaches. The transsphenoidal route is the surgical approach of choice for most sellar tumors because of the relationship of the sphenoid bone to the nasal cavity below and the pituitary gland above. More recently, extended approaches have expanded the indications for transsphenoidal surgery by using different corridors leading to specific target areas, from the crista galli to the spinomedullary junction.

Introduction And Objectives: Our aim was to study the radiological anatomy of the ethmoidal arteries.

Methods: A descriptive study was performed including CT images of 20 cadaver heads. The specimens were perfused with a radiopaque material and various anatomical parameters were analysed.
