Imaging Studies VII: Vascular Imaging01:19

Imaging Studies VII: Vascular Imaging

37
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...

Imaging Studies for Cardiovascular System IV: CMRI

70
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

167
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...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's...

Ultrasonography01:17

Ultrasonography

4.6K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Area of Science:

  • Biomedical Imaging
  • Medical Physics
  • Oncology

Background:

  • Mammography is the standard for breast cancer screening but cannot detect all lesions.
  • There's a need for complementary imaging techniques to improve breast cancer detection.

Purpose of the Study:

  • To investigate dynamic infrared breast imaging for detecting breast cancer.
  • To analyze the thermal response of the vascular system to stimuli.

Main Methods:

  • Utilized far-infrared thermography to map skin temperature.
  • Employed signal inversion and component analysis on dynamic thermal data.
  • Converted heat propagation into a virtual wave to identify thermal reflections.

Main Results:

  • Obtained clear images of passive thermal reflection and response to vasomodulation.
  • Observed that vasoconstriction magnitude may correlate with cancer presence in preliminary data.

Conclusions:

  • Dynamic infrared breast imaging shows promise as a complementary tool for breast cancer detection.
  • Further research with clinical data is needed to validate this imaging paradigm.
