Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

771
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...

Skin Cancer01:30

Skin Cancer

5.2K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

256
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...

Imaging Studies VII: Vascular Imaging

133
DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

316
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...

Imaging Studies for Cardiovascular System III: X-Ray01:20

Imaging Studies for Cardiovascular System III: X-Ray

362
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:

  • Medical Physics
  • Radiology
  • Cardiology

Background:

  • Long interventional radiology (IR) and interventional cardiology (IC) procedures can lead to high skin doses and injuries.
  • Accurate measurement and localization of peak skin dose (PSD) are essential for patient follow-up and safety.

Discussion:

  • Various software solutions exist for calculating PSD, with reported accuracies within ±25% in phantom studies.
  • Accuracy of calculated PSD is poorer in patient studies compared to phantom studies.
  • Similarities and differences among software packages highlight areas for improvement.

Key Insights:

  • Software-based PSD calculation accuracy requires enhancement, particularly in clinical settings.
  • Manufacturers of both software and IR systems need to improve their products.
  • Medical physicists play a vital role in optimizing and verifying dose monitoring software.

Outlook:

  • Future research should focus on improving the accuracy and reliability of PSD calculation software.
  • Enhanced software accuracy will contribute to better patient management and reduced risk of skin injuries.
  • Collaboration between software developers, IR/IC system manufacturers, and medical physicists is key to advancing patient safety.
