Radiological Investigation III: Pulmonary Angiogram and PET Scan

138
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 I: X-ray and CT

325
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

Area of Science:

  • Radiology
  • Oncology
  • Medical Informatics

Background:

  • Breast carcinoma is a leading cancer in women globally, with early detection crucial for improving survival rates.
  • Mammography is a cost-effective, sensitive imaging tool for early breast cancer diagnosis.
  • Existing public mammography datasets lack diversity and comprehensive clinical data, including biopsy confirmation and molecular subtypes.

Purpose of the Study:

  • To address the limitations of current datasets by creating a diverse, open-access mammography database.
  • To provide a valuable resource for research in breast cancer detection, diagnosis, and treatment.
  • To promote advancements in artificial intelligence and machine learning applications in medical imaging.

Main Methods:

  • Construction of the Chinese Mammography Database (CMMD) using online breast mammography data.
  • The CMMD comprises 3712 mammographies from 1775 patients.
  • The database is divided into two subsets: CMMD1 (biopsy-confirmed tumor types) and CMMD2 (known molecular subtypes).

Main Results:

  • The CMMD dataset includes 2214 mammographies with biopsy-confirmed benign or malignant tumor types (CMMD1).
  • The CMMD dataset includes 1498 mammographies with known molecular subtypes (CMMD2).
  • The database enriches the diversity of available mammography data for research.

Conclusions:

  • The CMMD represents a significant contribution to the field of breast cancer research by offering a diverse and clinically annotated dataset.
  • This database facilitates further development in early breast cancer detection and the study of molecular subtypes.
  • The CMMD aims to accelerate research and improve outcomes in breast carcinoma diagnosis and treatment.
