Ruolo dell’imaging TC nella valutazione post-mortem dei soggetti deceduti per caduta da altezze elevate: nostra esperienza

The CT-v can therefore be considered an effective method as an aid in the autopsy evaluation of individuals who died for various causes; in particular, in the case of deaths due to accidental falls from high altitudes, is able to identify the primary cause of death and all the epiphenomena due to precipitation

Imaging of hepatocellular carcinoma recurrence after liver transplantation

Liver transplantation (LT) provides the highest survival benefit to patients with unresectable hepatocellular carcinoma (HCC). The Milan criteria have been developed for the selection of LT candidates with the goal of improving survival and maintaining an acceptable risk of HCC recurrence. Despite this, recurrence of HCC after LT occurs in up to 20% of cases and represents a major concern due to the poor prognosis of these patients. Furthermore, several extended criteria for the selection of LT candidates have been proposed to account for the growing demand for organs and the resultant increase in the risk of HCC recurrence. Radiologists should be aware that HCC can recur after LT with multiple organ involvement. Knowledge of the location and radiologic appearance of recurrent HCC is necessary to ensure the choice of the most appropriate therapy. This paper aims to comprehensively summarize the spectrum of HCC recurrence after LT and to examine and discuss the imaging features of these lesions. CRITICAL RELEVANCE STATEMENT: This paper aims to share a review of imaging findings of HCC recurrence after LT and to make radiologists familiar with the spectrum of this disease

PATIENTS' KNOWLEDGE AND AWARENESS OF RADIATION DOSE AND RISKS FROM CT: DO PATIENTS NEED A PERSONALIZED COMMUNICATION OF DOSE BILL?

In the last decades exposure to ionizing radiations in computed tomography (CT) has constantly increased. Only a few years ago it was quite difficult to assess how much radiation had been delivered to a patient during a CT examination. Nowadays, the technical challenges of dose data reporting between CT scanners from different vendors have been met, making dose tracking a reality since these dose data are automatically stored in the picture achieving system of the radiology department. Most authors affirm communication of CT risk to patients should be personalized, but no studies investigate if a tailored communication is needed. Aim of our study is to understand how patients' characteristics may condition the comprehension of this information

THE ROLE OF DWI SEQUENCES IN PRECLINICAL INVESTIGATIONS OF THE SACROILIAC JOINTS ANOMALIES IN PATIENTS WITH CROHN'S DISEASE. OUR EXPERIENCE

The purpose of this study is to establish the role to confer to diffusion weighted sequences (DWI) in the detection of early stage of sacroileitis in patients with Crohn's Disease (CD)

EFFICACY OF RAW IMPLEMENTATION AND REDUCTION DOSE PROTOCOLS IN CT COLONOSCOPY: A SINGLE CENTRE 4 YEARS RETROSPECTIVE REVIEW.

CT Colonoscopy, or Virtual Colonoscopy, is well known as an effective alternative in patients that cannot sustain classic colonoscopy. Otherwise as all radiological procedure concerns arise for radiation exposure related to the examination. If CT colonoscopy is considered necessary the radiation dose, according to ALARA principle should be the lowest. For this reason we examined retrospectively our dose performance in CT colonoscopy in terms of CTDIvol and DLP considering the efficacy of different dose reduction factors

MRI DEFECOGRAPHY: TECHNIQUE, INDICATIONS AND CLINICAL FINDINGS NOT ONLY IN OBSTRUCTED DEFECATION SYNDROME

This education poster aims to share our personal experience about the MRI defecography, even though there is no general agreement about the technical and methodical details of the exam, also to improve knowledge about when and how is important to suggest MRI

Biphasic pleural mesothelioma in a electrician working in a railway company: case report and current trends in mesotheliomas in Italy

Background: Mesothelioma is an aggressive tumour that can involve the pleura, the peritoneum, and sometimes other mesothelia, such as the pericardium and the tunica vaginalis testis. Scientific communities have known for a long time the causal correlation between exposure to asbestos (work related or not) and the onset of the disease (in 75% - 90% of cases) and the increasing number of asbestos-correlated mesotheliomas expected in the next years. Case presentation: The authors present the case of an electrician, 66-year-old man, died for pleural mesothelioma, working in Palermo in the company of the Italian Railways for a period of about 20 years, exposed to asbestos. Frequently he disassembled and reassembled the ceiling lights in the train carriages and worked in the same workplace where it was made the asbestos removal from train carriages. The autopsy showed a biphasic pleural mesothelioma, with mainly polymorphic desmoplasticsarcomatous aspects, infiltrating the lung parenchyma, with areas of septal fibrosis and multiple outbreaks of pneumonia and edema. Conclusions: It is fundamental to know workers’ risks to formulate a correct etiopathogenetic diagnosis, as in this presented case, not apparently in connection with asbestos (electrician worker). Because of the long latency in the genesis of mesothelioma after asbestos exposure (both because of the work and environmental pollution), it is considered appropriate to increase in Italy the activities of the regional centres of the Health System dedicated to health promotion and health surveillance of the former exposed to asbestos, created and active, unfortunately, only in some regions of our Country

Imaging of hepatic hemangioma: from A to Z

The hemangioma is the most common solid lesion of the liver. Therefore, radiologists must know the typical and atypical imaging findings of this lesion in order to reach a correct diagnosis and avoid diagnostic errors. However, only few papers have comprehensively described the entire spectrum of atypical and uncommon imaging features. In this updated review, we provide the imaging features of hepatic hemangioma, in both typical and atypical forms, as well as its association with abnormalities in the adjacent hepatic parenchyma and other hepatic lesions, and its complications

Complete written/oral information about dose exposure in CT: is it really useful to guarantee the patients’ awareness about radiation risks?

Aims and objectives: According to the European directive 2013/59/Euratom, starting from February 2018, the information relating to patient exposure will be part of computed tomography (CT) reports, but the impact of this information on patients has not been deeply evaluated. Aim of our study was to evaluate patients’ perception of radiation exposure related to routine CT and their understanding after communication of their dose exposure. Materials and methods: A survey, investigating patient’s knowledge of radiation dose, was given to all adult patients (> 18 years) undergoing a CT examination both before and after CT scan. The first survey was the same for all patients. After CT scan, a second questionnaire was administered (after receiving the CT dose bill report and medical written and/or explanation about ionizing radiation risk). Results of the pre- and post-CT questionnaires responses were compared according to demographics characteristics and among the four post-CT groups. Results: For some questions, statistically significant differences were found between the two centres. Seventy per cent of the patients answered that the presence of CT parameters in the report is considered useful. Even if not always statistically significant there was a slight increase in awareness of ionizing radiation risk comparing the pre- and post-CT surveys. The group that had both written and oral explanations had a better comprehension of CT dose bill (group III vs. I, p = 0.002). Conclusion: The way of communication of ionizing radiation risks did not affect the results of the post-CT survey. Indeed, the interest in the topic did not rise in the post-CT survey in any of the group. Adequate information about ionizing radiation risks provided together with dose exposure information may be useful. However, there is not a standardized better way of communicating information on ionizing radiation risks due to CT

Optimizing liver division technique for procuring left lateral segment grafts - new anatomical insights

Left liver lobe (left lateral segment) grafts (LLG) is currently the most commonly used graft to transplant children (2/3 of cases currently in Europe); it is prepared by liver division (DL) in both living (LD) and deceased donors (DD) settings. Technically speaking, classical DL is through the parenchyma of segment IV - dividing the main left glissonean pedicle left to the main biliary confluence (trans-hilar (TH) approach): historically, this technique was introduced by Bismuth and Pichlmayr in 1988 in DD setting, and applied one year later for the first successful living donor transplantations by Strong (Figure 1)
