Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

A physical therapist (PT) aims to restore function or prevent additional impairment in a patient following an injury or disease. Massage, heat, cold, water, sonar waves, exercises, and electrical stimulation are some treatments used by PTs to treat...

Radiation: Applications

Radiation: Applications

The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.
The average...

Biological Effects of Radiation

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...

Summary

Speech-Language Pathologists (SLPs) performing video-assisted fluoroscopy of swallowing (VFSS) received minimal radiation exposure (0.15 mR per exam) when using lead aprons and maximizing distance. These findings reinforce radiation safety practices for SLPs.

Medical Imaging
Radiation Safety
Speech-Language Pathology

Background:

Video-assisted fluoroscopy of swallowing (VFSS) is a common diagnostic tool used by Speech-Language Pathologists (SLPs).
SLPs performing VFSS are exposed to ionizing radiation, necessitating awareness of safety guidelines.
Minimizing radiation exposure for both patients and healthcare professionals is crucial.

Purpose of the Study:

To quantify radiation exposure experienced by SLPs during clinical VFSS procedures.
To provide practical recommendations for maintaining radiation doses as low as reasonably achievable (ALARA).

Main Methods:

Radiation exposure was measured in six SLPs at an acute-care university hospital over 130 VFSS examinations.
Dosimetry badges were worn on lead aprons at chest level to record radiation doses.
Fluoroscopy times and examination types (pharynx only vs. pharynx and intrathoracic viscera) were documented.

Main Results:

The average fluoroscopy time per procedure was 165 seconds.
The average radiation dose to the SLP's dosimeter was 0.15 mR (0.0015 mGy) per procedure.
SLPs utilized lead shielding and maintained distance from the radiation source during procedures when feasible.

Conclusions:

Clinical VFSS procedures result in low radiation exposure for SLPs when established safety measures are employed.
Reinforcing practices such as shielding and increasing distance is vital for effective radiation safety in VFSS.
The study provides empirical data supporting the importance of radiation protection for SLPs.
