Radiological Investigation I: X-ray and CT01:30

Radiological Investigation I: X-ray and CT

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 the...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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 for Cardiovascular System III: X-Ray

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...
X-ray Imaging01:24

X-ray Imaging

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...
Ultrasonography01:17

Ultrasonography

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 a...
Radiological Investigation II: MRI and Ventilation Perfusion Scan01:30

Radiological Investigation II: MRI and Ventilation Perfusion Scan

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...

Area of Science:

  • Sports Medicine
  • Orthopedics
  • Regenerative Medicine

Background:

  • Injection therapy is a long-standing method for sports injury rehabilitation.
  • Athletes prioritize rapid return to sport, often seeking pain reduction and accelerated healing.
  • Various pharmacological agents and bioactive substrates are employed in these treatments.

Purpose of the Study:

  • To review available pharmacological agents and bioactive substrates for sports injury injection therapy.
  • To critically evaluate the evidence base supporting the use of these agents in common sports injuries.
  • To discuss the efficacy and limitations of current injection therapies.

Main Methods:

  • Comprehensive literature review of studies on injection therapies for sports injuries.
  • Analysis of evidence for pharmacological agents and bioactive substrates.
  • Assessment of quantifiable effects and limitations of current treatments.

Main Results:

  • A wide array of agents are used, but robust evidence for quantifiable effects is often lacking.
  • Some agents face restrictions, impacting their clinical application.
  • The current evidence base for efficacy in common sports injuries varies significantly.

Conclusions:

  • While injection therapy is integral to sports injury recovery, the evidence supporting many agents needs strengthening.
  • Further research is required to establish efficacy and guide optimal clinical practice.
  • Careful consideration of available evidence and potential restrictions is crucial when selecting treatments.
