Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

74
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

86
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Tuberculosis IV

123
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Imaging Studies for Cardiovascular System III: X-Ray

114
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Area of Science:

  • Natural Language Processing
  • Artificial Intelligence in Medicine
  • Radiology Informatics

Background:

  • Pulmonary embolism (PE) is a life-threatening condition requiring prompt diagnosis.
  • Manual extraction of PE diagnoses from radiology reports is labor-intensive.
  • Automated solutions using advanced NLP models are needed to enhance efficiency and accuracy.

Purpose of the Study:

  • To develop and evaluate an automated system using GPT-4o for extracting PE diagnoses from radiology report impressions.
  • To enhance clinical decision-making and streamline healthcare workflows.
  • To compare GPT-4o's performance against a baseline Clinical Longformer model.

Main Methods:

  • Two approaches were developed: a fine-tuned Clinical Longformer and a GPT-4o-based extractor.
  • Clinical Longformer, an encoder-only model, was trained on 1000 radiology reports.
  • GPT-4o, a decoder-only LLM, was validated on 200 reports, with postdeployment assessment on 200 operational records.

Main Results:

  • GPT-4o demonstrated superior performance over Clinical Longformer, achieving a sensitivity of 1.0 and an F1-score of 0.975 on the validation set.
  • Postdeployment evaluation showed GPT-4o maintained high accuracy with 1.0 sensitivity, 0.94 specificity, and 0.97 F1-score.
  • The high accuracy suggests a significant reduction in manual review and improved diagnostic precision.

Conclusions:

  • GPT-4o offers an effective and reliable method for automated PE diagnosis extraction from radiology reports.
  • This technology can significantly improve patient outcomes by expediting diagnosis and treatment.
  • The system has the potential to revolutionize clinical decision-making for critical conditions.
