Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

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.

Area of Science:

Interventional Radiology
Abdominal Imaging
Minimally Invasive Surgery

Background:

Image-guided splenic interventions are underutilized due to perceived complication risks.
Splenic biopsy and drainage can avoid surgical splenectomy for diagnosis and treatment.
Oncology patients benefit from splenic biopsy for focal mass diagnosis.

Purpose of the Study:

To review the efficacy and safety of various image-guided percutaneous splenic interventions.
To highlight the role of these procedures as alternatives to splenectomy.
To discuss the techniques and limitations of interventional procedures in the spleen.

Main Methods:

Review of literature on image-guided splenic biopsy (core biopsy, fine-needle aspiration).
Evaluation of image-guided catheter drainage for infected splenic collections.
Assessment of image-guided alcohol ablation for splenic cysts.
Discussion of percutaneous thrombin injection for splenic artery pseudoaneurysms.
Consideration of radiofrequency ablation (RFA) for splenic neoplasms and hypersplenism.

Main Results:

Core biopsy offers the highest yield for splenic tissue diagnosis.
Fine-needle aspiration has the lowest complication rate for splenic biopsy.
Image-guided drainage is an effective alternative to splenectomy for infected splenic collections.
Alcohol ablation is effective for splenic cysts; RFA data is limited.
Percutaneous thrombin injection is a viable treatment for splenic artery pseudoaneurysms.

Conclusions:

Image-guided splenic interventions, including biopsy, drainage, and ablation, are highly successful.
These minimally invasive techniques offer effective management options for various splenic pathologies.
Understanding interventional techniques and limitations is crucial for safe and effective splenic procedures.
