Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

392
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...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

213
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...

Computed Tomography01:10

Computed Tomography

5.8K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

161
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...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Imaging Biological Samples with Optical Microscopy01:18

Imaging Biological Samples with Optical Microscopy

5.1K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Oncology

Background:

  • Colposcopy is crucial for diagnosing and managing cervical lesions.
  • Deep learning models are increasingly used in cervical cancer screening tools.

Purpose of the Study:

  • To develop and validate a deep learning model (Unet + SVM) for classifying cervical lesions from colposcopy images.
  • To assess the model's performance in predicting cervical cancer risk.

Main Methods:

  • Utilized public and private colposcopy image datasets.
  • Employed Unet for lesion segmentation and SVM for classification.
  • Collected clinical data including PAP smear cytology and HPV testing results.

Main Results:

  • The CAD system achieved a DICE of 50% for segmentation and 58% accuracy for classification.
  • Sensitivity and specificity for classification were 70% and 48.8%, respectively.
  • Statistical comparison showed no significant difference between the CAD tool and expert colposcopists (p=0.597).

Conclusions:

  • The current CAD system requires improvement for widespread clinical adoption.
  • The model shows promise for improving cervical cancer diagnosis in resource-limited settings.
  • Further research with larger datasets and advanced deep learning methods is recommended.
