CT exposure in adult and paediatric patients: a review of the mechanisms of damage, relative dose and consequent possible risks.
An increase has been observed not only in the absolute number of CT examinations but also in the length of coverage and number of scanning phases, with the result that exposure to ionising radiation from CT is becoming an increasingly serious problem. The extent of the problem is not entirely known and cannot be adequately addressed without proper knowledge of all the phases that leads to the effective dose calculation. In light of the growing awareness of the issue of ionising radiation dose and the possible risk for the individual and the population, there is a need for radiologists, medical physicists and radiographers to play an active role in dose management. In this review, the author…
Imaging of metabolic and overload disorders in tissues and organs
Metabolic and overload disorders are a heterogeneous group of relatively uncommon but important diseases. While imaging plays a key role in the early detection and accurate diagnosis in specific organs with a pivotal role in several metabolic pathways, most of these diseases affect different tissues as part of a systemic syndromes. Moreover, since the symptoms are often vague and phenotypes similar, imaging alterations can present as incidental findings, which must be recognized and interpreted in the light of further biochemical and histological investigations. Among imaging modalities, MRI allows, thanks to its multiparametric properties, to obtain numerous information on tissue compositi…
Clinical indications for the use of cardiac MRI. By the SIRM Study Group on Cardiac Imaging
Cardiac magnetic resonance (CMR) is considered an useful method in the evaluation of many cardiac disorders. Based on our experience and available literature, we wrote a document as a guiding tool in the clinical use of CMR. Synthetically we describe different cardiac disorders and express for each one a classification, I to IV, depending on the significance of diagnostic information expected.
Impact of coronavirus disease 2019 (COVID-19) outbreak on radiology research: An Italian survey
Abstract Purpose To understand how COVID-19 pandemic has changed radiology research in Italy. Methods A questionnaire (n = 19 questions) was sent to all members of the Italian Society of Radiology two months after the first Italian national lockdown was lifted. Results A total of 327 Italian radiologists took part in the survey (mean age: 49 ± 12 years). After national lockdown, the working-flow came back to normal in the vast majority of cases (285/327, 87.2%). Participants reported that a total of 462 radiological trials were recruiting patients at their institutions prior to COVID-19 outbreak, of which 332 (71.9%) were stopped during the emergency. On the other hand, 252 radiological tri…
CT enterography as a powerful tool for the evaluation of inflammatory activity in Crohn’s disease: relationship of CT findings with CDAI and acute-phase reactants
Few studies have correlated computed tomography enterography (CTE) findings with Crohn’s disease (CD) clinical and biochemical activity. The aim of this study was to evaluate correlations between CTE findings with CD activity. The CTE datasets from 62 patients were retrospectively reviewed for different parameters: bowel wall thickening and hyperenhancement, mesenteric alterations, abdominal free fluid and complications related to the disease (fistulas, strictures, abscesses). Activity was assessed using the Crohn’s Disease Activity Index (CDAI) and some biochemical markers (C-reactive protein, erythrocyte sedimentation rate, alpha 2-globulins, fibrinogen, platelets, haemoglobin). Correlati…
