Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...

Summary

Modern imaging-guided biopsy techniques like core biopsy and vacuum-assisted biopsy have largely replaced surgical biopsies for diagnosing breast cancer detected via mammography. Radiologists are crucial for early diagnosis and staging using these advanced methods.

Area of Science:

  • Radiology
  • Oncology
  • Pathology

Context:

  • Breast cancer screening programs increasingly detect suspicious lesions via mammography.
  • Traditional fine-needle aspiration cytology is still used but often superseded by advanced techniques.
  • Minimizing invasive procedures is a key goal in breast cancer diagnostics.

Purpose:

  • To review the evolution and current applications of imaging-guided percutaneous biopsy techniques in breast cancer diagnosis.
  • To highlight the role of radiologists in utilizing these advanced diagnostic tools.
  • To emphasize the diagnostic accuracy and reduced invasiveness of modern biopsy methods.

Summary:

  • Imaging-guided percutaneous biopsies, including core biopsy and vacuum-assisted biopsy, are now standard for diagnosing mammography-detected breast lesions.
  • These techniques, guided by ultrasonography, stereotaxy, or MRI, offer high reliability and have reduced the need for surgical biopsies.
  • Radiologists are central to early histological diagnosis and staging of breast cancer using MRI and sentinel node biopsy.

Impact:

  • Improved diagnostic accuracy for early-stage breast cancer.
  • Reduced patient morbidity through minimally invasive procedures.
  • Enhanced role of radiologists in multidisciplinary breast cancer care.
