Imaging Studies III: Computed Tomography

175
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 for Cardiovascular System IV: CMRI

235
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

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...

Summary

Image-guided injections for shoulder MR arthrography (MRA) are more accurate and tolerable than non-image-guided methods. Ultrasound (US) guidance offers a less painful, rapid, and safe alternative to fluoroscopy (FL) for improved MRA diagnostic quality.

Area of Science:

  • Radiology
  • Medical Imaging
  • Orthopedics

Background:

  • Shoulder MR arthrography (MRA) is crucial for diagnosing internal derangements.
  • Accurate intra-articular contrast injection is essential for MRA efficacy.
  • Anterior injection techniques include fluoroscopy (FL), ultrasound (US), and non-image-guidance, but direct comparisons are lacking.

Purpose of the Study:

  • To prospectively compare the accuracy and performance of FL-guided, US-guided, and non-image-guided anterior intra-articular contrast injections for shoulder MRA.

Main Methods:

  • 210 patients with suspected shoulder pathology were randomized into three groups (70 each) for MRA.
  • Techniques compared: anterior intra-articular contrast injection under FL-guidance, US-guidance, or without image-guidance.
  • Evaluated parameters included needle placement accuracy, success rate, pain (VAS score), procedure time, contrast extravasation, joint distension, and MRA diagnostic efficacy.

Main Results:

  • Image-guided injections (FL and US) demonstrated 100% accuracy, significantly higher than non-image-guided (85.7%).
  • US-guidance was associated with the least pain, improved first-attempt success rates, and reduced contrast extravasation compared to non-image-guided techniques.
  • Procedure times differed significantly between FL and US guidance, with US being faster; both image-guided methods showed better outcomes than non-image-guided.

Conclusions:

  • Image-guided injections significantly enhance accuracy and patient comfort for shoulder MRA.
  • US guidance presents a less painful, rapid, and safe alternative to FL guidance.
  • Utilizing imaging guidance is recommended for precise needle placement, optimal joint distension, and superior MRA diagnostic quality.
