Lateral Recumbent or Prone Positioning for PET of the Urinary Bladder
Abstract:
Evaluation of the urinary bladder on PET with F-FDG is hampered by accumulation of activity in the urinary bladder due to physiological excretion of F-FDG in urine. We present 2 examples that demonstrate the utility of delayed scanning in lateral recumbent or prone position to improve evaluation of the bladder by differentiating between active bladder wall lesions and intraluminal activity. Changing the body position from a supine to a lateral recumbent or prone position can result in migration of intraluminal activity due to gravitational force, whereas F-FDG uptake in bladder wall lesions will show no migration.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
