207 Background: Multi-detector computed tomography using pancreatic protocol (pCT) has been a preferred diagnostic imaging modality before resection of the pancreatic ductal adenocarcinoma (PDAC), because an adjunctive role of liver magnetic resonance imaging (MRI) is still unclear. The current study evaluated whether liver MRI added to pCT can help to select proper surgical candidates, and reduce the risk of early recurrence, eventually result in longer survival in resected PDAC patients. Methods: Among 197 PDAC patients who underwent curative-intended surgery, 167 patients who achieved complete resection with no grossly visible tumor were enrolled retrospectively. All patients had no metastatic lesions on pCT and/or MRI, preoperatively. Among them, 102 patients underwent pCT alone (CT group), and 65 patients liver MRI as well as pCT (MRI group). Results: By adding the liver MRI, hepatic metastases were newly discovered in 3 of 58 patients (5.2%) with no hepatic lesions on pCT and in 17 of 53 patients (32.1%) with indeterminate hepatic lesions on pCT. Among 167 patients who achieved R0/R1 resection, the median overall and disease-free survival were 20.1 vs 29.3 months and 8.5 vs 10.0 months in the CT and the MRI group, respectively (p = 0.011 and = 0.012), during median follow-up of 16.4 months. 80 (78.4%) patients in the CT group and 39 (60.0%) in the MRI group experienced recurrence during follow-up. Cumulative initial hepatic recurrence rate was higher in the CT group than in the MRI group (43.7% vs 18.5% at 1yr and 57.4% vs 26.9% at 2yr, p < 0.001), although the other sites recurrence did not differ in both groups. Conclusions: Liver MRI added to pCT has an incremental value in detecting PDAC hepatic metastases. Furthermore, because PDAC patients who underwent resection after liver MRI as well as pCT expect lower rate of hepatic recurrence and better survival than pCT alone, therefore, liver MRI added to pCT is needed to patients who planned curative resection of PDAC.

Background: Radiological imaging methods used at a large scale in the assessment of hepatic lesions include: Ultrasound, computed tomography and magnetic resonance. To further characterize these lesions, specific contrast agents may be added, thus revealing the vascularity of the lesions. Discussion: This review focuses on gadoxetic acid, which is a hepatospecific contrast agent used in MRI. The aim of the review is to briefly explain the mechanism of GA enhancement, describe the enhancement patterns of some benign and malignant hepatic lesions and discuss possible advantages of GA over standard contrast agents. Conclusion: The role of GA in functional MR cholangiography and the idea of accessing liver function by measuring parenchymal enhancement will also be explained.

A többszeletes spirál-CT-berendezések széles körű alkalmazása és a perfúziós szoftverek bevezetése lehetővé tette az agyi véráramlás CT-vizsgálatát. Cél és módszerek: A szerzők ismertetik az agyi perfúziós CT-vizsgálatok elvét, technikáját, amelyet az elmúlt másfél évben 96 betegükön végzett vizsgálatuk tapasztalataival egészítenek ki. A folyamatos technikai fejlődés eredményeként a közeljövőben lehetővé válik a teljes agy perfúziós CT-vizsgálata. Következtetések: Az agy perfúziós CT-vizsgálata gyors, viszonylag olcsó és a stroke kórismézésében pontos diagnózist eredményez.

Abstract Background Although gall bladder perforation (GBP) is not common, it is considered a life-threating condition, and the possibility of occurrence in cases of acute cholecystitis must be considered. The aim of this study was to assess the role of multi-slice computed tomography (MSCT) in the assessment of GBP. Results It is a retrospective study including 19 patients that had GBP out of 147, there were 11 females (57.8%) and 8 males (42.1%), aged 42 to 79 year (mean age 60) presented with acute abdomen or acute cholecystitis. All patients were examined with abdominal ultrasonography and contrast-enhanced abdominal MSCT after written informed consent was obtained from the patients. This study was between January and December 2018. Patients with contraindications to contrast-enhanced computed tomography (CT) (pregnancy, acute kidney failure, or allergy to iodinated contrast agents) who underwent US only were excluded. Patients with other diagnoses, such as acute diverticulitis of the right-sided colon or acute appendicitis, were excluded. The radiological findings were evaluated such as GB distention; stones; wall thickening, enhancement, and defect; pericholecystic free fluid or collection; enhancement of liver parenchyma; and air in the wall or lumen. All CT findings are compared with the surgical results. Our results revealed that the most important and diagnostic MSCT finding in GBP is a mural defect. Nineteen patients were proved surgically to have GBP. Conclusion GBP is a rare but very serious condition and should be diagnosed and treated as soon as possible to decrease morbidity and mortality. The most accurate diagnostic tool is the CT, MSCT findings most specific and sensitive for the detection of GBP and its complications.

AbstractAnatomy is the key to accurate imaging interpretation. It is essential for radiologists to thoroughly understand the normal anatomy and spatial relationships of the stomach and duodenum to accurately localize the site of abnormality. In this article, we describe in detail the gross and applied radiological anatomy of the stomach and duodenum, and the current role of various radiological investigations (including barium studies, endoscopic ultrasonography, computed tomography, and magnetic resonance imaging) in the evaluation of the diseases involving the stomach and duodenum.
