Ultrasound Guided Biopsy Protocol
28
Feb

Overview

Real time ultrasound guidance improves accuracy and safety for soft tissue breast thyroid and abdominal biopsies.

Preprocedure Planning

Review imaging, coagulation status and plan needle trajectory to avoid vessels and critical structures.

Technique and Safety

Use sterile technique local anesthesia coaxial or core needle systems and post procedure compression and monitoring for complications.

Specimen Handling and Documentation

Label specimens clearly, document needle path images and provide clinical history to pathology for optimal diagnostic yield.

Endoscopic Ultrasound EUS
4
Feb

Overview

EUS combines endoscopy and ultrasound to visualize gastrointestinal wall layers and adjacent structures with the ability to perform fine needle aspiration.

Technique

Radial and linear echoendoscopes provide different views. FNA and FNB enable tissue diagnosis under direct ultrasound guidance.

Clinical Uses

Pancreatic mass evaluation staging of GI cancers and drainage of fluid collections.

Limitations and Safety

Invasive procedure with sedation risks. Requires endoscopic and sonographic expertise.

Image Guided Biopsy and Ablation
4
Feb

Overview

Image guided biopsies and thermal ablations use ultrasound CT or MRI guidance to obtain tissue or treat focal lesions with precision.

Technique

Needle trajectory planning real time imaging and post procedure monitoring ensure safety and diagnostic yield.

Clinical Uses

Liver lung and kidney biopsies tumor ablation for hepatic renal and pulmonary lesions.

Limitations and Safety

Bleeding infection and nondiagnostic samples are risks. Multidisciplinary planning optimizes outcomes.

C Arm Fluoroscopy Mobile C Arm
4
Feb

Overview

C arm systems provide real time fluoroscopy in operating rooms and procedure rooms for orthopedic vascular and pain procedures.

Technique

Image intensifier or flat panel detectors variable geometry and pulsed fluoroscopy optimize dose and image quality.

Clinical Uses

Fracture fixation spinal procedures vascular access and image guided pain interventions.

Limitations and Safety

Radiation exposure to staff. Shielding and positioning reduce occupational dose.

Interventional Radiology Imaging
4
Feb

Overview

Interventional radiology uses fluoroscopy CT ultrasound and cone beam CT to perform embolization ablation biopsies and vascular interventions.

Technique

Multimodality imaging guides access device placement and treatment monitoring with emphasis on sterile technique and radiation safety.

Clinical Uses

Tumor embolization vascular stenting image guided biopsies and drainage procedures.

Limitations and Safety

Procedural risks include bleeding and contrast reactions. Multidisciplinary planning and informed consent are essential.
