INTRODUCTION Polycysticovarian syndrome (PCOS) is a common endocrine disorder characterized by a variety of symptoms like hyperandrogenism, hyperinsulinaemia, menstrual dysfunction, unique ultrasonographic ovarian pattern and infertility [1]. Antral Follicle count (AFC) has been found to be reliable marker for ovarian reserve [2]. Since women with PCOS are extremely sensitive to gonadotrophin stimulation, knowledge of age related AFC normogram is clinically relevant. Wiser et al., published age-related normogram for AFC in women with PCOS using transvaginal ultrasound and found that the decline in number of AFC as the age progresses was linear and slower in PCOS when compared to infertile women without PCOS [2]. We used magnetic resonance imaging (MRI) instead of TVS, since MRI can acquire three dimensional images, not operator dependant and also it can be performed in patients for whom transvaginal ultrasound could not be performed like in unmarried women. The main objective of our study is to create an age related normogram for AFC (AFC) in women with PCOS and to compare that with women without polycystic ovarian syndrome using MRI. MATERIALS AND METHODSThis descriptive cross-sectional study was conducted after obtaining clearance from Institutional Ethics Committee between January 2013 to July 2015. The goal of the study was to create an age related normogram of AFC in women with PCOS and to compare it with those without PCOS using MRI. Women between the ages of 18 to 45 were included in the study. A total of 1500 women were examined, out of which 400 fitted the criteria for

We report a rare case of intracranially protruded posterior and superior semicircular canals beyond the margins of temporal bone with bony roof dehiscence in bilateral posterior and left superior semicircular canals in a patient with benign paroxysmal positional vertigo (BPPV).

AIM:To determine the role of MDCT-Coronary angiography in the evaluation of coronary artery anomalies and to calculate the prevalence of coronary artery anomalies in a subset of south Indian population. MATERIALS AND METHODS: This is a retrospective study. Data of 250 consecutive patients who underwent CT coronary angiography in our institution over a period of 2 years were collected and analysed. The studies are analysed for the presence of abnormal origin and course of the arteries. Presence of anomalies of intrinsic coronary arterial anatomy like myocardial bridging were also evaluated. Few of these patients also underwent catheter coronary angiography and those findings were also included for analysis. RESULTS: Out of 250 patients, 7 patients had anomalies of origin and course of coronary arteries, 9 patients had myocardial bridging. Of these 16 patients, 10 patients underwent catheter coronary angiography which gave less information than CTcoronary angiography. CONCLUSION: The incidence of coronary artery anomalies in a subset of south Indian population was 6.4% and MDCT-Coronary angiography better evaluated these anomalies than catheter coronary angiography.

BACKGROUNDMDCT is a very useful investigative technique for all liver pathologies. The conspicuity of a liver lesion on CT depends on the attenuation difference between the lesion and the normal liver. The difference in blood supply results in different enhancement patterns between various liver tumours in the various phases of contrast enhancement. Intravenous contrast is needed to increase the conspicuity of lesions. Multidetector computed tomography with plain, arterial, portal venous and delayed phase is very useful in identifying and characterising various liver lesions depending on their vascular nature. In our study, we evaluated the role of Multidetector computed tomography in the characterisation of liver lesions in patients presenting to our hospital.
