Prognostic factors of worse outcome for hospitalized COVID-19 patients, with emphasis on chest computed tomography data: a retrospective study.

Objective: To evaluate anthropometric and clinical data, muscle mass, subcutaneous fat, spine bone mineral density, extent of acute pulmonary disease related to COVID-19, quantification of pulmonary emphysema, coronary calcium, and hepatic steatosis using chest computed tomography of hospitalized patients with confirmed diagnosis of COVID-19 pneumonia and verify its association with disease severity.

Methods: A total of 123 adults hospitalized due to COVID-19 pneumonia were enrolled in the present study, which evaluated the anthropometric, clinical and chest computed tomography data (pectoral and paravertebral muscle area and density, subcutaneous fat, thoracic vertebral bodies density, degree of pulmonary involvement by disease, coronary calcium quantification, liver attenuation measurement) and their association with poorer prognosis characterized through a combined outcome of intubation and mechanical ventilation, need of intensive care unit, and death.

Results: Age (p=0.

Physician-patient communication in diagnostic examinations: what is the role of the radiologist?

Historically, radiology has developed in a way that has increasingly distanced the radiologist from the patient. Currently, diagnostic imaging results are predominantly communicated through written reports. Written communication is not considered sufficient, verbal communication being essential for the performance of the modern radiologist to be considered satisfactory.

Role of computed tomography at a cancer center emergency department.

To evaluate the imaging methods used at the emergency department (ED) of a cancer center, with emphasis on computed tomography (CT). A descriptive, retrospective, single-center study was conducted by reviewing imaging exams and medical records, after approval of the institution's Ethics Review Board. The demographic data, cancer history, and imaging exam requested were evaluated for all patients and the indications and results of head, chest, and abdominopelvic CT scans were also evaluated.
