This study aims to collect data by multidetector computed tomography (MDCT) on the diameter of the normal common bile duct (CBD) and the diameter of CBD after cholecystectomy. In this retrospective study, CBD measurements were performed on axial oblique images, perpendicular to the long axis of the distal CBD. The mean diameter of the normal CBD was measured in 604 patients without cholecystectomy. The patients were divided into 6 groups according to their age. Analysis of variance (ANOVA) was used to compare data obtained from the six age groups. The mean diameter of the CBD of 46 patients who had cholecystectomy was calculated. The results were compared with age matched control group by Students t test. The largest diameter of CBD ranged from 1.8 to 11.8mm. The mean of the largest diameter of 604 subjects was 4.77 ± 1.81. The diameter of the CBD significantly increased with age. Mean largest CBD diameters of postcholecystectomy subjects (7.28 ± 2.37) were significantly greater than age matched control group. In conclusion the diameter of CBD shows a considerable increase with age. The largest diameter of the CBD is up to 6mm in most of the subjects. An upper limit of 8mm appears reasonable after the age of 50; and an upper limit of 10mm seems appropriate for cholescystectomized subjects.

ABSTRACT The vascular calcification regulators and inflammatory markers including fetuin-A, osteopontin (OPN), and matrix Gla protein (MGP) may play an important role in the development of intracerebral hemorrhages (ICHs). So far, the relationship between these parameters and ICH has not been studied. Therefore, this study was designed to elucidate whether fetuin-A, MGP, and OPN are involved in the pathophysiology of ICH. The ICH group consisted of 27 consecutive patients with spontaneous ICH evaluated in the neurology intensive care unit within the first 24 hours from the onset of the stroke. The serum OPN levels were significantly increased in patients with ICH compared to the controls. On the other hand, the serum MGP and fetuin-A levels were significantly decreased in the patients with ICH in comparison to the controls. In the patients with ICH, the serum MGP levels of the nonsurvivors were statistically significantly lower than the MGP levels of the survivors. In conclusion, the change in serum fetuin-A, MGP, and OPN levels after ICH indicates that these parameters play a role in the pathophysiological processes leading to an ICH. Measurement of the serum MGP levels may also be of value to estimate mortality.

ZusammenfassungDie Lungenvenen sind eine der bedeutendsten Strukturen des Kreislaufs. Im letzten Jahrzehnt wurde erkannt, dass die Lungenvenen eine bedeutende Rolle beim Vorhofflimmern als auslösender Fokus der elektrischen Aktivität spielen. Die primäre Behandlungsmethode des Vorhofflimmerns ist die Ablation des Fokus in den Lungenvenen. Für den besten Erfolg dieser Maßnahme sollte die Anatomie der Lungenvenen vorher gut bekannt sein. MATERIAL UND METHODEN: In unserer Abteilung für Radiologie wurde zwischen Jänner 2008 und Mai 2010 bei 783 Patienten eine computertomographische Angiographie durchgeführt. Die Patienten waren zur Coronar-CT wegen einer bekannten oder suspizierten koronaren Herzerkrankung, bzw. zur CT Angio wegen des Verdachtes auf Pulmonalembolie zugewiesen worden. Alle Untersuchungen wurden auf einem Phillips Brilliance 64 Zeiler Multidetektor CT Gerät durchgeführt. 402 der Patienten waren männlich, 381 weiblich. Das mittlere Alter der Patienten lag bei 48 (14–89) Jahren. Die CT Ergebnisse zur Identifikation der Anatomie der Lungenvenen (inklusive ihrer Varianten und Anomalien) wurden retrospektiv erhoben. ERGEBNISSE: Bei dem Großteil der Fälle mündeten zwei Lungenvenen in den linken Vorhof auf jeder Seite. 18 Variationen wurden rechts und 8 Variationen links entdeckt. Die häufigste kombinierte Variante waren 2 rechts und 4 links (32,3 %) einmündende Lungenvenen. Vier links einmündende Lungenvenen war der häufigste Einfach-Variations Typ (76 %). Zusätzlich wurden ein Situs inversus totalis (0,12 %), 2 partiell anormale pulmonal venöse Rückströme (0,25 %) und ein Szimitar Syndrom (0,12 %) gefunden. SCHLUSSFOLGERUNGEN: Diese Studie zeigt, dass viele Variationen der Lungenvenen mit zunehmender Patientenzahl beobachtet werden. Um eine erfolgreiche und komplikationslose Ablation bzw. Operation zu gewährleisten, sollte die Anatomie der Lungenvenen vor der Prozedur bekannt sein. Die Multidetektor CT ist eine verlässliche bildgebende Methode für die Erfassung der Querschnitts und 3-dimensionalen Anatomie.SummaryPulmonary Veins are one of the major structures of circulation. In the last decade, pulmonary veins have been known to play an important role as the triggering focus of the electrical activity in atrial fibrillation. Primary treatment method of AF is RF ablation of the focus. For the best ablation, the anatomy of PVs should be well established before the procedure. MATERIAL AND METHODS: In our radiology department, 783 patients underwent computed tomography angiography between January 2008 and May 2010. Patients were referred for coronary CTA because of known or suspected coronary artery disease or computed tomography pulmonary angiography (CTPA) because of known or suspect pulmonary embolism. All scanning was performed on Philips Brilliance 64 slice Multidetector CT. The group consisted of 402 male and 381 female patients with the average age of 48 (range 14–89). CT data of patients were retrospectively reviewed to identify the PV anatomy and to determine anatomic variants and anomalies. RESULTS: In the majority of cases, two pulmonary veins drain into the left atrium on each side. Eighteen and eight variations were found in the right and left sides, respectively. Most frequent combined variations were 2R-4L (32.3%) and 4L was the more frequent single variation type (76%). In addition to that one Situs inversus totalis (0.12%), two partial anomalous pulmonary venous returns (0.25%) and one scimitar syndrome (0.12%) were found. CONCLUSION: This study showed that multiple types of variations of PVs can be found with increasing patient number. Therefore, for the successful ablation and surgery without any complications, the anatomy of PVs should be known before the procedure. MDCT is a reliable imaging method for the detailed cross-sectional and 3D anatomy.

Purpose: Renal artery variations are important for clinical reasons. The aim of this study is to determine the originating level and variations of renal arteries with 64-channel multidetector computed tomography (MDCT). Materials and methods: In a university hospital, 820 patients who underwent MDCT angiography of the abdominal aorta were retrospectively evaluated. The number, early division (ED), and originating level of renal artery were evaluated retrospectively. Variations of the renal artery on both sides, the difference between the genders with variations of the renal artery, were compared with chi-square test. Results: Renal artery originating from the level of L1–L2 intervertebral disc was found in 37.0% and 38.9% of patients on the right and left sides, respectively. Renal artery variations, including extrarenal artery (ERA), were found in 27% and ED in 26.7% of the patients. Significant differences were found in ED and ERA prevalence for genders (p = 0.006 and p = 0.043, respectively). The prevalence of both variations is higher in males. Conclusions: An awareness of renal vascular variations is very important for both surgeons and radiologists. In this series, renal arterial variations were found in approximately one-fourth of the study population.

PurposeThe aim of this study was to assess the cerebral variations and observe their frequency in the patients who have undergone angiographies with the state of the art 64-slice multidetector computed tomography (MDCT) angiography technique due to various reasons.Methods500 patients (253 women, 247 men) who had CT scan in the period of April 2008 to March 2010 at Dicle University Medicine Faculty Hospital Radiology Unit were surveyed in this study. Patients who had CT scan with brain CT angio protocol were evaluated using multiplanar, maximum intensity projection (MIP) and volume rendering (VR) images in work station.Results773 variations were totally detected among 500 patients. Variations were categorized as Willis polygon, fenestration and other variations. Frequent variations were detected at Willis polygon and posterior communicating artery (PCOA) hypoplasia was detected as the prevalent variation.ConclusionsIn the present study, we have demonstrated that cerebral vascular variations are frequent and that these variations can be detected in a non-invasive manner using the MDCT angiography. The results obtained from our study may serve as preoperative guidelines for the units performing surgical procedures.

BACKGROUND Nutritional vitamin B(12) deficieny is common among infants in the developing and underdeveloped countries. There is limited information concerning neuroimaging findings in infants with vitamin B(12) deficiency in the literature. AIMS The aim of this study is to evaluate the cranial magnetic resonance imaging (MRI) changes and clinical characteristics of hypotonic infants due to vitamin B(12) deficiency. MATERIALS AND METHODS A total of 15 infants with neuroradiologic investigations were diagnosed with nutritional B(12) vitamin deficiency. Cranial MRI was performed on all infants. RESULTS Five infants were female (33%) and the mean age of infants was 12.3 ± 5.5 months. Hypotonia and neurodevelopmental retardation were present in all patients. MRI demonstrated thinning of the corpus callosum in 6 (40%), cortical atrophy in 5 (33.3%), large sylvian fissures in 5 (33.3%), ventricular dilatation in 3 (20%), asymetric large lateral ventricle in 2 (13.3%) and delayed in myelination in 2 (13.3%) patients. Four infants had normal MRI findings. CONCLUSION Because of the importance of vitamin B(12) in the development of the brain, MRI findings may be detected and useful in infants with vitamin B(12) deficiency.

Most malignant tumors of the heart are metastatic. Metastatic cardiac tumors are usually associated with Wilms tumor, neuroblastoma, and non-Hodgkin lymphoma in children (Br J Radiol 71:336-339). Osteosarcoma rarely metastasizes to the heart. Twenty-four cases have been reported in the literature so far. The right side of the heart is more commonly involved than the left, and the pericardium and/or myocardium is more frequently involved than the endocardium (Br J Radiol 71:336-339). We report a rare case of osteogenic sarcoma of the right femur with left ventricular metastases presenting with ventricular tachycardia that has not been reported previously. Cardiac tumors are extremely rare, found at a frequency of only 0.001% to 0.28% at autopsy series. The incidence of secondary cardiac tumors is much higher than that of primary cardiac tumors [1]. Secondary intracardiac neoplasms arise most frequently from renal cell carcinoma, bronchogenic carcinoma, Wilms tumor, chondrosarcoma, and osteogenic sarcoma [2]. There are several reports of metastatic childhood osteosarcoma involving the cardiac chambers. However, endocardial left cardiac chamber Fig. 1 Electrocardiogram prese 0735-6757/
