Improving infection control practices [4 steps]

Improving infection control practices [4 steps]

As most medical practitioners and administrators know, infection control remains no easy task. Rather than being a single action, such as disinfection, infection control encompasses a variety of steps that come together to form a cohesive process. This process, many times referred to as an organization or facility’s infection control protocol, should include a series of preventative measures that touch upon a variety of instances where patients find themselves at risk of infection.  Whether it be minimizing direct transmission through the use of medical gloves or indirect [...]

Choosing the right ultrasound transducer. Different types of ultrasound probes for ultrasound-guided procedures.

Choosing the right ultrasound transducer

Ultrasound imaging is one of the most widely used imaging modalities. The ultrasound transducer, also referred to as a probe, is the device used to produce the ultrasound image.   The transducer works by producing sound waves that bounce off body tissues and create echoes. The device then receives the echoes and transmits them to a computer that converts them into an image called a sonogram.   Ultrasound imaging is used in a variety of medical contexts, ranging from OB/GYN applications to surgical [...]

Best Practices for Radiology Departments during COVID-19

As medical imaging modalities continue to be used to examine potential and confirmed COVID-19 cases, radiology practitioners find themselves on the frontlines. The use of ultrasound and CT to diagnose and monitor the progress of treatment signifies that medical imaging professionals risk being exposed to the respiratory virus due to their close contact with patients. In an effort to combat the risk of transmission, the Radiological Society of North America (RSNA) recently released a set of best practices for radiology departments during [...]

Can an ultrasound scan detect cancer?

Can an ultrasound scan detect cancer?

Ultrasound is one of the most widely used diangostic imaging techniques. When it comes to diagnosing cancer, physicians typically use ultrasound as the first step in the diagnostic process. The ultrasound technique offers a variety of benefits. Ultrasound scans are cost-effective and can be carried out fairly quickly when compared to other imaging tests, such as MRI and CT scans. Perhaps more importantly, ultrasound does not expose the patient to any radiation. Nonetheless, when compared to CT and MRI, the images produced by ultrasound offer less clarity and detail. Ultimately, [...]

3 Ways to Improve Hospital Disinfection

In hospitals across the United States, hospital-acquired infections continue to be a top of mind concern for infection prevention professionals. The CDC reports that 1 in 25 hospital patients in the U.S. contracts a hospital-acquired infection per year, and that number grows when you include patients treated in other healthcare settings such as clinics. The CDC has categorized healthcare-acquired infections, a broader term which encompasses all healthcare facilities, as a “winnable battle” and has set out a variety of guidelines for preventing their spread. To prevent the spread of infections in hospitals, infection preventionists with these facilities [...]

Can Remdesivir shorten COVID-19 recovery?

Does Remdesivir shorten coronavirus recovery?

Researchers have found an experimental drug that may shorten the recovery time for patients with the COVID-19 infection. The drug, called remdesivir, has been found to interfere with the replication of some viruses, including COVID-19. On April 29th, Anthony Fauci, the director of the US National Institute of Allergy and Infectious Disease (NIAID), reported that a clinical trial of more than a thousand patients on remdesivir resulted in an average recovery time of 11 days, in contrast to 15 days for a placebo. “Although a 31% improvement doesn’t seem like a [...]

Ultrasound for joint, muscle, and bone exam vs mri in diagnostic imaging

Ultrasound vs. MRI for bone and muscle problems

In cases where aches and pains are rooted in a problem with the patient’s musculoskeletal system, the physician may order a diagnostic imaging test to determine the cause. There are multiple types of diagnostic imaging techniques at a physician’s disposal, such as ultrasound, computed tomography (CT) scans, magnetic resonance imaging (MRI), and x-rays. Depending on the needs of the clinician, ultrasound may provide some advantages over its sister techniques for musculoskeletal conditions. “Some common reasons we do musculoskeletal ultrasound are to [...]

Research finds dangerous blood clots linked to COVID-19

Research finds blood clots in COVID-19 cases

In a recent issue of the RSNA’s journal, Radiology, a special report outlined the prevention, diagnosis, and treatment of complications stemming from blood clots in COVID-19 patients. In addition, the journal published two research letters and a case study on the topic.  As COVID-19 spreads throughout the world, clinicians have been forced to face the virus with no proven treatment options. Physicians combatting the respiratory virus have utilized diagnostic imaging, such as ultrasound and CT, as they attempt a variety of different treatment options and tailor their approach on a case-by-case basis.    Due to [...]

Possible ultrasound treatment for Alzheimer's disease

New research reveals potential ultrasound treatment for Alzheimer’s

At the 2019 meeting of the Radiological Society of North America (RSNA), researchers offered key insights into how focused ultrasound can potentially be a safe and effective way to target and open areas of the blood-brain barrier. Doing so could permit for new treatment approaches to Alzheimer’s disease.  The blood-brain barrier is a network of blood vessels and tissues that stops foreign substances from entering the brain. The barrier poses a challenge for scientists researching Alzheimer’s treatments, because it does not allow potentially therapeutic medications to reach target areas within the brain.  Many researchers have been looking [...]

Ultrasound protection for COVID-19

AIUM releases guidelines for ultrasound protection and disinfection during COVID-19

Due to the nature of the COVID-19 pandemic, physicians have been ordering imaging scans to examine and diagnose patients with symptoms of the respiratory virus. As diagnostic imaging professionals are called upon to perform scanning, infection control and ultrasound disinfection practices have become an urgent concern for both the safety of the clinician and the patient. The highly contagious COVID-19 virus can be transmitted through the air and surfaces. Many physicians have turned to ultrasound as a method of diagnosing patients and monitoring confirmed cases. Ultrasound scans such as [...]
