The brain's natural GPS system
This year's (2014) Nobel prize for medicine was awarded for the discovery of the function of a relatively poorly known part of the human (and animal) brain called the hippocampus. Studies by the Nobel award winning scientists show that the hippocampus is responsible for the function of locating and guiding humans through various geographical locations.Just when we docs and medics thought we knew it all, we discover that we knew ever so little, after all.But that applies to all of science. :-)Read what the BBC has to say about it:http://www.bbc.com/news/health-29504761Also a report in the NY Times:http://www.nytimes.com/201...

A large ureteric calculus
This large right upper ureteric calculus presented little difficulty in being imaged. Measuring 15 mm in size, I managed to get an adequate window to capture these images. The right kidney, predictably, shows moderate hydronephrosis also. (Source: cochinblogs)

Case of pelvic Right kidney
This 40 year old male patient has a surprise in his abdomen. The right kidney is located in the right side of the pelvis, which is a variation from the normal. The normal position of the kidneys is the lumbar region. The right kidney should be seen in right renal fossa close to the liver. This variant is called pelvic kidney with this organ located just to the right of the urinary bladder.see: http://www.ultrasound-images.com/kidneys.htm#Ectopic/%20Pelvic%20kidney (Source: cochinblogs)

Normal lower limb venous doppler study- using convex probe
very often while performing venous Doppler study, imaging conditions are poor due to oedema of the lower limbs with the result that it is nearly impossible to visualise adequately the veins using a high frequency linear ultrasound probe. In these conditions, the use of our convex probe of lower frequency like the one we used for the lower limb venous Doppler study, is the only practical alternative. And indeed, the results are quiet good, even impressive with a 3.5 MHz probe. Of course, when needed, one must change the PRF settings as the situation demands.This was a normal venous Doppler study of the right lower lim...

the left femoral vein- colour Doppler study
this elderly male patient had redness and mild swelling of the skin over the middle third of the left leg.This is what we found when we did the colour Doppler study of the left lower limb.This patient did not have any major pain or tenderness in the thigh.Clinically, he did not have features of deep vein thrombosis. Would you think of this possibility from these Doppler ultrasound images? ...

Is this a nodular subcortical heterotopia- neonatal brain ultrasound
This neonate shows a large (3.5 cms.) sized lesion in the Rt. cerebral hemisphere. What do these neonatal brain ultrasound images portray? Is it a case of neonatal nodular subcortical heterotopia or is it an ICSOL due to intracerebral bleed or some form of glioma?the answer: this is a large intracerebral haematoma occupying the right parietal and occipital regions of the neonate ' s brain. This was the diagnosis based on the MRI scan.See:http://www.ultrasound-images.com/Pediatric.htm#Intracranial%20hemorrhageSee this link:Radiology (AJNR) article on disorders of cortical formation (Source: cochinblogs)
