Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

335
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

945
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...

Difference from Background: Limit of Detection01:05

Difference from Background: Limit of Detection

8.0K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

433
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...

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...

Area of Science:

  • Medical Imaging
  • Radiological Protection
  • Interventional Cardiology

Background:

  • Interventional cardiology procedures utilize fluoroscopy, leading to significant radiation exposure for patients and operators.
  • Managing radiation doses during these procedures is a critical challenge for healthcare professionals and regulatory bodies.
  • Establishing local diagnostic reference levels (DRLs) is essential for optimizing radiological practices.

Purpose of the Study:

  • To establish local diagnostic reference levels (DRLs) for interventional cardiology procedures in Morocco.
  • To optimize radiation doses and enhance radiological practices within the study's scope.
  • To provide benchmarks for radiation exposure in coronary angiography and percutaneous transluminal coronary angioplasty.

Main Methods:

  • The study analyzed 657 interventional cardiology procedures (coronary angiography and percutaneous transluminal coronary angioplasty) in Rabat, Morocco (2017-2018).
  • Data collected included patient demographics, dose area product (PKA), air kerma (Kar), fluoroscopy time (FT), and beam parameters (kV, mAs).
  • Local DRLs were determined using the 75th percentile of PKA and FT for each procedure type.

Main Results:

  • Mean PKA values were 29.2 Gy*cm² for CA and 70.4 Gy*cm² for PTCA.
  • Mean fluoroscopy times were 4.0 min for CA and 12.17 min for PTCA.
  • Local DRLs were established at 37.3 Gy*cm² (PKA) and 4.48 min (FT) for CA, and 87.1 Gy*cm² (PKA) and 16.15 min (FT) for PTCA.

Conclusions:

  • This study successfully proposed local DRLs for coronary angiography and percutaneous transluminal coronary angioplasty in Morocco.
  • The established DRLs align with findings from international studies, indicating comparable radiation dose levels.
  • The proposed DRLs serve as a valuable tool for optimizing radiation safety in Moroccan interventional cardiology.
