Abstract:
Fifty preterm newborn infants with gestational age of 28-36 weeks were subjected to real time cranial sonography to (a) evaluate the ventricular system and brain parenchyma, (b) determine the incidence of intracranial abnormalities, and (c) to establish the utility and advantages of routine cranial sonography in preterm infants. The lateral ventricular width varied from 6-12 mm (8.67 +/- 1.85 mm) while hemispheric width ranged between 3.68 to 3.95 cm with a mean of 3.84 +/- 0.25 cm. The lateral ventricular ratio ranged from 20.9 to 26.4% and it showed progressive decrease with increasing gestational age. Cavum septum pellucidum was found in 68% of the preterms. Incidental intracranial pathologies were detected in 12% of the preterms screened.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
