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 III: Computed Tomography

893
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...

Area of Science:

  • Urologic oncology
  • Radiology
  • Medical imaging

Background:

  • Prostate cancer is a common malignancy often diagnosed late.
  • Early detection and accurate staging are crucial for effective management.
  • Advanced imaging modalities are transforming prostate cancer diagnosis.

Purpose of the Study:

  • To review the principles, benefits, and clinical applications of mpMRI, microUS, and PSMA PET/CT.
  • To evaluate these technologies in biopsy-naïve patients, those with prior negative biopsies, and under active surveillance.
  • To highlight their role in localized prostate cancer diagnosis and management.

Main Methods:

  • Comprehensive literature review of recent studies and guidelines.
  • Focus on diagnostic accuracy and clinical utility of mpMRI, microUS, and PSMA PET/CT.
  • Analysis of applications in various patient subgroups and clinical scenarios.

Main Results:

  • Multiparametric MRI (mpMRI) shows high sensitivity for clinically significant prostate cancer (csPCa).
  • Micro-ultrasound (microUS) demonstrates comparable sensitivity and specificity to mpMRI in early studies.
  • Prostate-specific membrane antigen positron emission tomography-computed tomography (PSMA PET/CT) is highly sensitive and specific for staging and detecting metastases.

Conclusions:

  • mpMRI, microUS, and PSMA PET/CT enhance prostate cancer diagnosis, staging, and management accuracy.
  • These advanced imaging techniques facilitate precise lesion targeting for biopsies and therapy planning.
  • Further research, including randomized controlled trials, is necessary to optimize their integration into prostate cancer care.
