In this study, we have used the Breast Screen Reader Assessment Strategy (BREAST) platform to facilitate 27 radiologists in reading a case set of 60 digital mammograms, 20 of which included cancers. Each case consisted of the four standard cranio-caudal (CC) and medio-lateral oblique (MLO) projections. All radiologists were registered to read mammograms at their workplace by the Jordanian Ministry of Health. Each reader was asked to locate any malignancies, provide a confidence rating using a scale of 1 - 5, and identify the type of appearance. All images were displayed using 8 MP monitor, supported by radiology workstations with full image manipulation facilities. Results were evaluated using Jackknife Alternative Free-Response Receiver Operating Characteristic (JAFROC). Demographics obtained from each radiologist regarding their experience, qualifications and breast-reading activities were correlated against JAFROC scores using Spearman techniques. The results showed that the mean JAFROC score was 0. 52 (95% confidence interval (CI): 0.46, 0.58);location sensitivity score was 0. 41 (95% CI: 0.41, 0.56);specificity score was 0.73 (95% CI: 0.68, 0.83). Higher performance in term of JAFROC scores was directly related to number of years since professional qualification (r = 0.433;p = 0.024), number of years reading breast images (r = 0.62;r = 0.001) and number of mammography images read per year (r = 0.69;p = 0.001). On the other hand, higher performance was inversely linked to the frequency of reading other modalities per week (r = -0.48;p = 0.010). No other statistical differences were significant. Finally, higher radiologists’ performance in cancer detection is correlated with increasing the number of mammograms reads per week.展开更多

Radiologists can contribute substantially in evaluation and treatment of patients with a gunshot wounds. Plain films, CT, Angiography, and sometimes MR imaging are used to localize shots. This paper describes a case report of shotgun injury to the face and neck and also attempts to illustrate the spectrum of available imaging with relevant findings pertaining to bullets and shotgun pellets in gunshot injuries. Radiologists should be aware of the associated complications and forensic implications when they take on the task of interpreting these images.展开更多

Previous work has reported that radiology has a reasonable incidence of error, a number of which are resulted from observer mistakes. The radiologists’ interaction with the image is critical, and studying the types of diagnostic errors to improve patient and radiologist wellbeing, reduce cost and improve the public perception of the health care system is well justified. Therefore, the aim of current review is to consider the primary types of diagnostic errors in radiology, as well as their causes and implications with a focus on mammographic misdiagnosis.展开更多

It is a cancer which does not extend beyond the muscularis layer of the gallbladder and it is characterized in almost of cases by the absence of lymph node and visceral invasion. Patients and Method: We have conducted this retrospective study of all our cases of early gallbladder cancer treated in our surgical unit. We have studied these through clinical, morphological, therapeutical and evolutionary aspects. Results: Of 202 gallbladder carcinoma, 33 cancers were classified as early cancer. 25 were females and 8 were males. The mean age was 56.4 years (41 -?70 years). All patients were free of gallbladder cancer symptoms and all except one had normal CEA and CA19.9. 2 patients had synchronous tumors (one colonic cancer and one rectal cancer). For 16 patients, the diagnosis was done by ultrasonography and 17 by histological examination of the specimen removed for biliary lithiasis. 8 patients had PT1a tumor (confined only to mucosa) and 25 had PT1b tumor (tumor infiltration of the muscular layer). For 19 patients who benefited from extensive lymphadenectomy, only one (5.3%) had lymph node infiltration. 16 patients had a simple cholecystectomy and in two cases, the cholecystectomy was associated with bile duct resection. 17 patients had hepatectomy with extensive lymphadenectomy. 2 patients had a simultaneous right colectomy and abdominoperineal resection and another one benefited from choledocal cyst resection. 3 patients benefited from stone removal from bile duct and two had tumor removal from bile duct (ruptured tumor in the bile duct). 1 patient (3.7%) died in postoperative course (hospital mortality). In the follow-up period, 4 patients died from intercurrent causes. Two patients presented a recurrence at 14 and 36 months and died respectively at 19 and 42 months. One patient presented a bile duct cancer at 66 months. She died at 78 months after palliative treatment. Currently, 22 patients (66.7%) are still alive without recurrence with mean and median survival of 53 and 31 months. Conclusion: Early gallbladder cancer is an entity which must be known by the radiologist and the surgeon. Recognized on time and well treated, early gallbladder cancer can be cured and its prognosis is excellent.展开更多
