The fetal MCA PI and RI showed a parabolic curve with plateau at 28-30 weeks of gestation. A significant correlation was noted between MCA PI and RI with gestational age. UA PI and RI showed a gradual fall over the gestational age with a strong negative correlation. There was a significant correlation between MCA PI and UA PI with their respective RI values. CP ratio has also shown a parabolic curve with turning point at 31-32 weeks of gestation. A significant correlation was noted between CP ratio and gestational age. CP ratio also showed a minimal positive correlation with MCA PI and a strong negative correlation with UA PI.

Chylothorax is an extremely rare but potentially life-threatening complication of radical neck dissection. Its rarity makes surgeons unfamiliar with its management. We report the case of a bilateral chylothorax occurring after a left radical neck dissection and discuss its management. A multi-disciplinary approach is advocated, involving surgical, respiratory and dietetic input, and this led to a favourable outcome for our patient.

Tubercular spondylitis or Pott's spine is an extrapulmonary form of tuberculosis which affects the spine. MRI is the imaging modality of choice not only in diagnosing the condition but also in guiding the surgical management. The cases of spinal tuberculosis were systematically analyzed for various pathological lesions which are produced in the spine as the disease progresses.

In this paper, adaptive windowing based segmentation scheme has been proposed. The image has been partitioned into different windows and the windows to be segmented, have been fixed by three criteria. The first one is based on pyramid approach where, the preselected windows are merged based on entropy measure. The second one is based on incremental window selection method. In the third criterion, the preselected windows are merged based on entropy measure. The windows thus fixed are considered as sub-images and each sub-image has been segmented based on the notion of rough entropy and granular computing. The algorithm could segment the images with uneven lighting condition.
