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...

Background:

Lung cancer is a leading cause of cancer mortality worldwide.
Accurate lung nodule detection in CT images is crucial for early diagnosis but remains challenging due to nodule size, background complexity, and image noise.

Purpose of the Study:

To develop a novel weighted bidirectional recursive pyramid algorithm for enhanced lung nodule detection in CT images.
To address challenges including small nodule size, large background regions, and complex lung structures.

Main Methods:

Proposed a weighted bidirectional recursive feature pyramid network (BiPRN) for improved feature extraction and multi-scale information fusion.
Developed a CBAM_CSPDarknet53 module integrating an attention mechanism for spatial and channel feature aggregation.
Applied the BiPRN and CBAM_CSPDarknet53 to YOLOvX models (YOLOv3, YOLOv4, YOLOv5) for lung nodule detection experiments on LUNA16 and LIDC-IDRI datasets.

Main Results:

The BiRPN-YOLOv5 model achieved a high sensitivity of 98.7% on the LUNA16 dataset.
The same model demonstrated a sensitivity of 96.2% on the LIDC-IDRI dataset.

Conclusions:

The proposed weighted BiPRN and CBAM_CSPDarknet53 algorithm shows significant potential for improving lung nodule detection sensitivity.
This advancement could enhance early lung cancer detection in clinical practice.
