Imaging Studies VI: Voiding Cystourethrography and Cystography01:22

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...

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. Intravenous Urography (IVU)Intravenous...
Ultrasonography01:17

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Radiology
  • Orthopedics
  • Rheumatology

Background:

  • The sacroiliac (SI) joint presents unique imaging challenges, often leading to equivocal radiographic findings for sacroiliitis.
  • SI joint pathology is common in osteoarthritis and inflammatory spondyloarthropathies like ankylosing spondylitis.
  • Other conditions such as hyperparathyroidism, athletic injuries, pregnancy-related changes, and sacroiliac joint dysfunction can affect the SI joint.

Purpose of the Study:

  • To review the diagnostic imaging modalities for sacroiliac joint pathology.
  • To discuss the imaging features of sacroiliitis and related conditions.
  • To highlight the role of image-guided injections in managing SI joint pain.

Main Methods:

  • Review of radiographic, computed tomography (CT), and magnetic resonance imaging (MRI) findings in SI joint pathology.
  • Discussion of clinical presentations associated with SI joint involvement.
  • Evaluation of therapeutic image-guided SI joint injections.

Main Results:

  • CT and MRI offer earlier detection of sacroiliitis and osteoarthritis compared to radiographs.
  • MRI is highly effective for diagnosing early sacroiliitis and monitoring treatment response.
  • Image-guided SI joint injections provide relief for patients with sacroiliac joint dysfunction and sacroiliitis.

Conclusions:

  • Advanced imaging techniques are crucial for accurate SI joint diagnosis.
  • Understanding the diverse causes of SI joint pain is essential for effective management.
