1.3K
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...

Imaging Studies II: Ultrasonography

835
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...

Ultrasonography

8.5K
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...

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

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,...

Area of Science:

  • Gynecologic imaging
  • Pelvic pain diagnosis
  • Emergency medicine

Background:

  • Adnexal torsion is a gynecologic emergency causing acute pelvic pain.
  • Ovarian torsion, often with cysts or masses, is common; tubal and other rare forms exist.
  • Accurate diagnosis is crucial for timely intervention and fertility preservation.

Purpose of the Study:

  • To review the multimodality imaging approach for adnexal torsion.
  • To highlight diagnostic challenges and common mimics of adnexal torsion.
  • To emphasize the importance of imaging in acute pelvic pain management.

Main Methods:

  • Review of current literature on adnexal torsion imaging.
  • Discussion of ultrasound, MRI, and CT findings.
  • Analysis of imaging features differentiating torsion from other conditions.

Main Results:

  • Characteristic imaging findings of adnexal torsion include ovarian enlargement, stromal edema, and peripherally displaced follicles.
  • Doppler ultrasound may show reduced or absent blood flow, but this is not always present.
  • Mimics such as ectopic pregnancy, appendicitis, and pelvic inflammatory disease require careful consideration.

Conclusions:

  • Multimodality imaging is essential for diagnosing adnexal torsion.
  • Recognizing limitations and mimics improves diagnostic accuracy.
  • Prompt imaging-guided diagnosis facilitates appropriate surgical management.
