Transesophageal Echocardiography Protocol
9
Feb

Overview

TEE offers superior visualization of posterior cardiac structures valves and the thoracic aorta using multiplane probe manipulation.

Indications and Preparation

Indicated for endocarditis evaluation intraoperative monitoring and thrombus detection. Fasting and sedation protocols are required.

Core Views and Measurements

Acquire mid esophageal four chamber two chamber long axis transgastric short axis and aortic arch views with Doppler assessment.

Safety and Documentation

Monitor sedation and airway status, document probe depth and image quality, and record findings relevant to procedural guidance.

Optical Endoscopy Fluorescence Imaging
4
Feb

Overview

Optical endoscopy with white light and fluorescence enhances mucosal visualization. Targeted fluorescent agents enable molecular imaging during procedures.

Technique

Narrow band imaging autofluorescence and targeted probes increase lesion contrast. Real time visualization guides biopsy and resection.

Clinical Uses

Gastrointestinal and pulmonary endoscopy intraoperative tumor margin assessment and sentinel node mapping.

Limitations and Safety

Agent safety and specificity vary. Interpretation requires training and adjunctive pathology.

Cone Beam CT CBCT
4
Feb

Overview

CBCT provides high resolution three dimensional imaging with compact systems used in dental ENT and interventional suites for localized volumetric imaging.

Technique

Cone beam geometry and flat panel detectors yield isotropic voxels. Field of view and exposure settings are tailored to the region.

Clinical Uses

Dental implant planning maxillofacial imaging and intraoperative imaging in hybrid operating rooms.

Limitations and Safety

Lower soft tissue contrast than conventional CT. Scatter and artifacts require careful technique.

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.
