Radiological Investigation III: Pulmonary Angiogram and PET Scan01:13

Radiological Investigation III: Pulmonary Angiogram and PET Scan

120
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

306
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...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

47
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

161
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 II: Positron Emission Tomography and Scintigraphy

182
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Summary

Skeletal scintigraphy (bone scan) use has shifted dramatically over 30 years. Indications now focus more on non-cancerous orthopedic and rheumatological issues rather than metastatic disease detection.

Area of Science:

  • Nuclear Medicine
  • Radiology
  • Medical Imaging

Background:

  • Skeletal scintigraphy, a common nuclear medicine procedure, has seen significant changes in its application over the last three decades.
  • Advancements in other imaging techniques, improved understanding of diseases, and updated clinical guidelines have influenced its use.

Purpose of the Study:

  • To analyze the evolution of indications for skeletal scintigraphy over the past 30 years.
  • To document the paradigm shift from metastatic to nonmetastatic applications.

Main Methods:

  • Retrospective analysis of skeletal scintigraphy indications.
  • Comparison of data from 1998 and 2021.

Main Results:

  • Indications for metastatic disease detection decreased from 60.3% in 1998 to 15.5% in 2021.
  • Nonmetastatic indications increased from 39.7% in 1998 to 84.5% in 2021.
  • A notable rise in nononcological orthopedic and rheumatological indications was observed.

Conclusions:

  • Skeletal scintigraphy is increasingly utilized for non-oncological conditions.
  • The role of bone scans has evolved, with a reduced emphasis on metastatic surveys.
