18fdg Synthesis And Supply: A Journey From Existing Centralized To Future Decentralized Models, Maseeh Uz Zaman, Nosheen Fatima, Zafar Sajjad, Unaiza Zaman, Rabia Tahseen, Areeba Zaman

Department of Radiology

Positron emission tomography (PET) as the functional component of current hybrid imaging (like PET/ CT or PET/MRI) seems to dominate the horizon of medical imaging in coming decades. 18Flourodeoxyglucose (18FDG) is the most commonly used probe in oncology and also in cardiology and neurology around the globe. However, the major capital cost and exorbitant running expenditure of low to medium energy cyclotrons (about 20 MeV) and radiochemistry units are the seminal reasons of low number of cyclotrons but mushroom growth pattern of PET scanners. This fact and longer half-life of 18F (110 minutes) have paved the path of a centralized …

A Randomized Control Trial Comparing Weight Adjusted Dose Versus Fixed Dose Prophylactic Phenylephrine Infusion On Maintaining Systolic Blood Pressure During Caeserean Section Under Spinal Anaesthesia, Lucy Wambui Mwaura

Master of Medicine in Anaesthesiology

Background: Spinal anaesthesia is the standard of care for elective caesarean delivery. Its advantages over general anaesthesia include: decreased blood loss, reduced postoperative pain and faster recovery time. Despite these advantages, the sympathetic blockade induced by spinal anaesthesia results in 80 percent incidence of hypotension without prophylactic management. This hypotension can cause: nausea, vomiting, cardiovascular collapse or even loss of consciousness in the mother, and fetal acidosis. Current evidence supports co-loading with intravenous fluids in conjunction with the use of vasopressors as the most effective way to prevent and treat the hypotension. Phenylephrine is the accepted vasopressor of choice in …
