Radiological Investigation III: Pulmonary Angiogram and PET Scan

614
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...

Endoscopic Procedures V: ERCP

5.2K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Radiological Investigation I: X-ray and CT

1.5K
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...

Area of Science:

  • Interventional Radiology
  • Gastroenterology
  • Oncology

Background:

  • Malignant biliary obstruction frequently arises from gallbladder carcinoma, cholangiocarcinoma, or metastatic nodes.
  • Percutaneous interventions are vital in managing patients with malignant biliary obstruction.

Purpose of the Study:

  • To outline the indications, contraindications, techniques, and complications of radiological interventions for malignant biliary obstruction.

Main Methods:

  • Review of percutaneous interventions including biliary drainage, cholecystostomy, and radiofrequency ablation.
  • Focus on the procedural aspects and clinical applications in malignant biliary obstruction.

Main Results:

  • Biliary drainage serves as a primary intervention, offering palliative care or pre-operative liver function improvement.
  • Other interventions like cholecystostomy and radiofrequency ablation are also discussed.

Conclusions:

  • Percutaneous radiological interventions are essential for managing malignant biliary obstruction.
  • Understanding the indications, techniques, and complications is key for effective patient management.
