Radiological Investigation III: Pulmonary Angiogram and PET Scan

722
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

3.5K
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.

Area of Science:

  • Radiology
  • Urology
  • Oncology

Background:

  • Prostate biopsies are standard for cancer diagnosis, typically using transrectal ultrasound (US) guidance.
  • Current methods involve blind sampling of 10-14 cores, often missing localized cancer lesions not visible on US.

Purpose of the Study:

  • To explore advanced imaging modalities for improving prostate biopsy accuracy.
  • To highlight the evolving role of radiologists in prostate cancer management through enhanced biopsy techniques.

Main Methods:

  • Review of proposed imaging methods including Color Doppler, US contrast agents, elastography, and magnetic resonance (MR) imaging.
  • Focus on MR imaging and MR imaging/US fusion for targeted prostate biopsies.

Main Results:

  • Advanced imaging offers potential for lesion-directed biopsies, overcoming limitations of standard US.
  • MR imaging and fusion biopsy enable more precise cancer detection and localization.

Conclusions:

  • Prostate MR imaging and fusion biopsy represent significant advancements in prostate cancer diagnosis.
  • These technologies empower radiologists in screening, diagnosis, targeted biopsy, surveillance, and focal therapy of prostate cancer.
