A Mumbai hospital has successfully performed a rare and intricate heart surgery on an 18-month-old child diagnosed with a ...

Ventilation–perfusion (V/Q) scintigraphy has a high sensitivity to detect embolic disease but its value has been challenged with the emergence of multidetector CT pulmonary angiography (CTPA). We ...

Pulmonary nodule quantification is essential in forecasting and diagnosing potential malignant nodules, providing critical information for early intervention and treatment planning. However, most ...

Background and objectives Acute occlusion of the internal carotid artery (ICA) accompanied by contralateral A1 segment agenesis (CA-A1) presents distinct clinical and radiological features.

A 68-year-old woman was referred for investigation of pulmonary artery hypertension. Right heart catheterisation was performed and the tip of the catheter was positioned in the right middle lobe ...
