Abstract:

Inflammatory myofibroblastic tumor of the bladder is rare. We described contrast-enhanced CT and FDG PET/CT findings in an inflammatory myofibroblastic tumor of myxoid-vascular pattern involving the bladder muscular layer and adventitia with extensive edema of the adjacent mucosa. The tumor showed hyperenhancement on postcontrast CT and high-grade activity with SUVmax of 31 on PET/CT. The thickened edematous mucosa showed isoenhancement and isometabolism relative to the normal bladder wall. This case indicates inflammatory myofibroblastic tumor should be included in the differential diagnosis of FDG-avid lesions of the bladder.

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1.

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
