Aim: To determine whether the apparent diffusion coefficient (ADC) measurements calculated values were significantly different between cervical tumors with different histological characteristics (type, degree of differentiation, and stage of malignancy). Patients and methods: MRI and DWI scans performed in 26 pathologically proved cancer cervix patients. ADC values of different pathological types of cervical cancer were compared. Student's t test was used for statistical analysis. Results: There were 18 squamous cell carcinoma and 8 adenocarcinomas showed with biopsy results. Early stage (FIGO-Ib-IIa, n = 7), (FIGO-IIb-IIIb-IVa, n = 19). The mean ADC values for squamous cell carcinoma (n = 18), and adenocarcinoma (n = 8) were 0.88 · 10 À3 , and 0.91 · 10 À3 mm 2 /s, respectively. Statistical analysis showed significant difference in ADC value between both tumor types (P < 0.05). There was also significant difference between the mean ADC values of the tumor grade I and the other grades (II, III) (p < 0.05). The mean ADC values in early stage cervical cancer (0.83 ± 0.05 · 10 À3 mm 2 /s) were significantly lower than the mean ADC values in late stage disease (0.98 ± 0.06 · 10 À3 mm 2 /s) (p < 0.05). Conclusion: ADC value measurements can provide useful information in diagnosis of cervical cancer as well as in preoperative assessment of the tumor stage.
SummaryBackgroundThe aim of the study is to emphasize the role of 128 MSCT angiography in the diagnosis of congenital cyanotic heart diseases.Material/MethodsThis study included sixty patients and was conducted from December 2014 to July 2016 in the Multidetector CT unit of Zagazig University hospitals. All images included axial, MPR, MIP, and VRT and were interpreted in one session. Pulmonary veins were assessed for PAPVR or TAPVR, PDA, cardiac apex and heart chambers, interatrial or interventricular septal defects, pericardium, and site and size of the great veins (IVC and SVC).ResultsThis study included 60 patients. Thirty-four were boys (56.7%), and 26 were girls (43.3%). The age ranged from nine months to five years, and the mean age was 34.5 months. We found the following anomalies: tetralogy of Fallot (15 patients, 25%), tricuspid atresia (12 patients, 20%), Ebstein’s anomaly (4 patients, 6.5%), pulmonic atresia or stenosis (7 patients, 11.5%), truncus arteriosus (6 patients, 10%), TGA (10 patients, 17%), and TAPVR (6 patients, 10%).ConclusionsMDCT proved to be an important modality for decision-making in patients with congenital cyanotic heart diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
