Adrenal Vein Sampling: How to Make It Quick, Easy, and Successful
Adrenal vein sampling has a reputation as a difficult procedure. However, it is being performed more frequently at some institutions due to the realization that primary aldosteronism is more common than previously believed. At the author’s institution, adrenal vein sampling with computed tomographic (CT) and laboratory correlation has been performed more than 800 times in the past 10 years.

Coil-Assisted Retrograde Transvenous Obliteration (CARTO) for the Treatment of Portal Hypertensive Variceal Bleeding: Preliminary Results
CARTO appears to be a technically feasible and safe alternative to traditional balloon-occluded retrograde transvenous obliteration or transjugular intrahepatic portosystemic shunt, with excellent clinical outcomes in treating portal hypertensive non-esophageal variceal bleeding.
Biliary Interventions Tools and Techniques of the Trade, Access, Cholangiography, Biopsy, Cholangioscopy, Cholangioplasty, Stenting, Stone Extraction and Brachytherapy
We describe an overview of the instrumentation and technical approaches for several fundamental biliary interventional procedures, including percutaneous transhepatic cholangiography and internal/external biliary drainage, endobiliary biopsy techniques, cholangioscopy, cholangioplasty and biliary stenting, biliary stone extraction, and intraluminal brachytherapy.
CT-Guided Bone Biopsy With a Battery-Powered Drill System: Preliminary Results
Standard percutaneous bone biopsy involves manual needle insertion. Recently, a battery-powered needle drilling biopsy system (OnControl) has been introduced. We report our experience using this drill biopsy system for CT-guided percutaneous bone biopsy in 25 patients.
Patients with chronic inflammatory lung diseases may experience massive hemoptysis. Surgical intervention is hazardous and often impossible in these patients, however endovascular management of hemoptysis with bronchial artery embolization is effective and well tolerated by these patients.
The aim of this article is to summarize the etiologies, pathophysiology, and the diagnostic and management strategies of hemoptysis as related to bronchial artery embolization. In addition, the techniques of arteriography and embolization as well as associated procedural outcomes and complications are delineated.

CT-Guided Celiac Plexus Neurolysis for Intractable Pain of Unresectable Pancreatic Cancer
This study explores the value of CT-guided celiac plexus neurolysis (CPN) using the anterior median approach and single puncture technique with ethanol injection as palliative treatment for alleviating intractable pain in patients with unresectable pancreatic cancer.
