Imaging Studies VI: Voiding Cystourethrography and Cystography

32
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...

29
IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

57
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 IV: Magnetic Resonance Imaging

27
Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...

Muscles of the Pelvic Floor and Perineum01:26

Muscles of the Pelvic Floor and Perineum

1.4K
The muscles of the pelvic floor and perineum are crucial for supporting the pelvic organs, controlling continence, and aiding in sexual function, childbirth, and core stability. They are typically divided into the superficial perineal layer and the deep pelvic floor layer.
Perineal Layer
The perineum is a diamond-shaped area below the pelvic diaphragm, divided into an anterior urogenital triangle that contains the external genitals and a posterior anal triangle housing the anus. The urogenital...

Area of Science:

  • Pelvic floor imaging
  • Functional imaging
  • Diagnostic imaging

Background:

  • Establishing normal imaging parameters for the pelvic floor is crucial for accurate diagnosis.
  • Total pelvic floor ultrasound (TPFUS) and defaecation MRI (dMRI) are advanced imaging modalities.
  • Understanding variations in asymptomatic individuals is key to interpreting findings in symptomatic patients.

Purpose of the Study:

  • To determine the range of normal imaging features observed during total pelvic floor ultrasound (TPFUS) and defaecation MRI (dMRI).
  • To assess the prevalence of specific pelvic floor abnormalities in asymptomatic female volunteers.

Main Methods:

  • Prospective investigation of 20 asymptomatic female volunteers (mean age 36.5 years).
  • Utilized both defaecation MRI (dMRI) and total pelvic floor ultrasound (TPFUS) including transperineal, transvaginal, endovaginal, and endoanal approaches.
  • Subjects completed validated symptom questionnaires; imaging was interpreted by blinded clinicians.

Main Results:

  • Abnormal findings were detected on both dMRI and TPFUS in asymptomatic subjects.
  • A high rate of functional features was observed on dMRI (12/20), with some also seen on TPFUS (4/20).
  • Specific findings included rectocoele, intussusception, enterocoele, and cystocoele in a subset of volunteers.

Conclusions:

  • The study demonstrates that abnormal imaging findings can be present in asymptomatic individuals using dMRI and TPFUS.
  • There is a wide spectrum of imaging findings in healthy subjects, emphasizing the need for careful interpretation.
  • While not large enough to redefine normal parameters, the findings are valuable for understanding variations in health.
