SUMMARY Purpose : Describer the imaging characteristics of esophageal cancer on MDCT 256-detector row. Material and method : From June 2019 to June 2020, 32 patients with esophageal cancer were treated at Huu nghi Hospital. The quantitative parameters were expressed as mean and standard deviation while the qualitative parameters were expressed as percentage. SPSS 26.0 was applied. Results: 3.1.% cases were not found on MDCT. The tumors were found most commonly in the middle and low one third. The tumor size were 44.8±33.01 mm of length and 12.2±4.77 mm of thickness. All of them were T3 stages. 48.4% patients have lymph nodes. Majority of lymph nodes were in mediastinum or supraclavicular areas. 9.6% patients were metastasized. Conclusion: MDCT 256-detector row is helpful for characterising esophageal cancer. Key words: esophageal cancer, computed tomography, staging.

SUMMARY Objective: The purpose of this study was to determinate the accuracy of multidetector computed tomography (MDCT) angiography for imaging evaluation of renal arterial and venous structures of living donor kidney Materials and Methods: Two hundred twenty-eight potential living donor candidates were included to this study, who had CTA for the assessment of their renal vessels in our hospital between January 2018 and June 2020 and one hundred-eighty donors who underwent open surgical in this time. The number, course, and drainage patterns of the renal vessel were retrospectively observed from the scans. Anomalies of renal arteries, veins and inferior vena cava (IVC) were recorded. Multiplanar reformations (MPRs), maximum intensity projections, and volume rendering were used for analysis. The results obtained were correlated surgically. Results: A total of 228 potential live kidney donors underwent renal CTA (112 of the patients were male, and 116 were female. Mean age of donors was 38,32 ± 12,34 years. among them 180 patients had donor nephrectomy. There were 151 kidneys had single renal artery , here were 29 kidneys had at least one accessory or polar artery. There were 45 early branching renal arteries, two kidneys were retroaortic left renal veins. 16 kidneys had multiple renal veins. 55 kidneys wewe late venous confluence of renal veins. Sn, Sp, NPV, PPV compare open oparative nephrectomy 87,5%- 100%. Conclusion: Renal CTA is an accurate, safe and noninvasive diagnostic tool for determination of renal artery and vein abnormalities in living kidney donors preooparative. It helps with surgery planning, choosing operation side and exclusion of donors. Keyword: CTA, MSCT, living donor

SUMMARY Aim: Evaluate the value of MRI with Gd-EOB-DTPA (Primovist) in the detection of HCC comparison with the pathological results Methods : Descriptive cross-sectional research, performed on 28 patients consist of 2 groups: Group I includes 18 patients with HCC and group II includes 10 non-HCC patients (7 patients with focal nodular hyperplasia. 3 patients with liver metastasis). The patients whose liver lesion were detected on diagnostic imaging modalities undergone MRI with hepatiobillial specific contrast agent Gd-EOB-DTPA (Primovist). Thereafter, definite diagnosis was based on histopathological results of biopsy or surgery. Results: Hepatobiillial phase hypointense was the most sensitive diagnostic criteria of HCC(94.4%), however, specificity is only 70%. For liver cancer diagnosing, arterial enhancement followed by washout on portal venous or late phase had the sensitivity, negative predictive value and diagnostic accuracy were 61.1%, 58.8% and 75%, respectively. When combining with hepatobillial phase hypointense, these values increased to 72.2%, 67.7%, and 82.1%, respectively; while, the specificity and positive predictive values were unchanged. Conclusion: Hepatobiillial phase hypointense is a good diagnostic criteria on detection of HCC than differential diagnosis with other hepatic lesions. The addition of hepatobiillial phase on MRI with Gd-EOB-DTPA (Primovist) increases the likelihood of detecting HCC lesions.

SUMMARY Esophageal varicose veins are the main cause of high GI bleeding in cirrhotic patients. Plug – assisted retrograde transvenous obliteration (PARTO) is a safe, minimally invasive, effective hemostasis technique and prevent recurrence in gastric variceal hemorrhage/ gastric varices that has been widely deployed in many countries such as Japan and Korea. Multislice Computer Tomography (MSCT) that provides complete information about the features of gastric varicose buns is the method that should be performed prior to PARTO intervention. Objectives: 1. Characterization of gastric varicose buns on multiseries computed tomography and Kiyosue classification. 2. Comparing multi-sequence computed tomography with DSA image of gastric varicose tufts in patients with PARTO retrograde intervention. Methods : The study was conducted retrospectively and with crosssectional descriptions of 91 patients with cirrhosis and gastric varices admitted to the hospital because of gastrointestinal bleeding were taken MSCT in the period from April 2018 to July 2020. Conclusion : Among 91 cases of gastric varices; the majority of gastric veins dilated to an average of 5-10 mm (51 patients), supplied mainly from the left gastric vein (84 patients) and drained to the esophageal veins (60 patients). The diameter of the dilated gastric vein measured on the MSCT was correlated with the number of afferent portal venous feeders and not with the number of efferent systemic venous drainage. The major gastric varicose tufts fall under the type 2B classification (~ 22%). Out of 91 cases, there were 58 cases with gastrorenal shunt, 2 cases with gastrocaval shunt, of which 21 cases of severe gastrointestinal bleeding required PARTO intervention; There were 2 cases where there was no renal shunt but had severe gastrointestinal bleeding, PVTO. For the PARTO intervention group, the renal shunt diameter measured on CLVT and measured on the DSA did not differ with p = 0.083. Results: The gastric varicose buns is mainly supplied with blood from the left gastric vein, and drained by the esophageal vein and the kidney shunt. Examination of imaging of gastric varicose buns is necessary to determine whether PARTO is indicated, to select the right materials and to effectively predict of PARTO interventions.
