Sonazoid™
Sonazoid™ is an ultrasound contrast agent (UCA) consisting of stabilized gas microbubbles in an aqueous suspension. Sonazoid™ has overcome the stability problems of first generation USCA and can produce myocardial perfusion images. Myocardial imaging using ultrasound contrast agents provides diagnosis of chronic heart disease and assessment of the coronary arteries and of the coronary blood flow reserve.
Sonazoid™ is taken up by healthy Kupffer cells in the liver and spleen, but break down in high amplitude ultrasound imaging modes such as color Doppler imaging. The bubble rupture produces a transient pressure wave, which results in a characteristic mosaic color pattern from tissues containing the microbubbles (induced acoustic emission). Liver tumors without Kupffer cells will not display the mosaic pattern and can therefore be identified easily.

Sonogram
The term 'sonogram' is often used interchangeably with 'ultrasound,' but it specifically refers to the resulting image or picture produced during a diagnostic ultrasound examination, also known as ultrasonography or sonography. It serves as a visual representation of the echoes detected by the transducer and provides detailed anatomical information about the area being examined. Sonograms are typically displayed on a monitor, printed on film, or stored digitally for further analysis and documentation by medical professionals such as sonographers and radiologists. They serve as invaluable diagnostic tools, aiding in the detection and evaluation of various medical conditions, as well as guiding interventions, ultrasound therapy, and treatment planning.
The term 'ultrasound' itself refers to the technology used during a sonogram, but it also finds several other applications beyond medical imaging. These include echolocation, crack detection, and cleaning, among others.

Sonographer
The field of medical imaging offers numerous career opportunities, and one profession is that of a sonographer. Sonographers play a critical role in healthcare by utilizing ultrasound technology to create images of the body's internal structures.
Becoming a Sonographer:
The educational and professional requirements for sonographers can vary from country to country. The duration of these programs can range from one to four years, depending on the country and level of qualification.
The typical path in the United States begins with obtaining a post-secondary education in diagnostic medical sonography from an accredited program. These programs usually result in an associate's or bachelor's degree. Coursework typically covers anatomy, physiology, medical ethics, ultrasound physics, and specialized sonography techniques. Additionally, students gain practical experience through clinical internships in healthcare facilities.
After completing their education, aspiring sonographers can choose to obtain professional certification through organizations such as the American Registry for Diagnostic Medical Sonography (ARDMS) or the American Registry of Radiologic Technologists (ARRT). Certification often requires passing examinations that assess knowledge and competency in specific areas of sonography.
Many countries also have certification or registration requirements for sonographers. These certifications are typically obtained through professional bodies or organizations specific to each country. Examples include the Canadian Association of Registered Diagnostic Ultrasound Professionals (CARDUP) in Canada, the Australian Sonographers Accreditation Registry (ASAR) in Australia, and the Society and College of Radiographers (SCoR) in the United Kingdom.
Job Description:
Sonographers are skilled professionals who operate ultrasound machines and perform sonograms on patients. They work closely with physicians and other healthcare professionals to provide accurate and high-quality diagnostic images. Using sound waves, sonographers capture images of organs, tissues, and blood flow patterns, which are then used by medical practitioners to diagnose and monitor various medical conditions.
Sonographers must have a comprehensive understanding of anatomy, physiology, and sonographic techniques to optimize image quality. They interact directly with patients, explaining procedures, addressing concerns, and ensuring patient comfort throughout the scanning process. Documentation of findings and communication with the medical team are also essential responsibilities.
Some aspect of the job can be demanding, while sonographers often spend long hours on their feet, positioning and maneuvering patients during scans. Dealing with patients who are in pain, anxious, or difficult to scan requires empathy, patience, and excellent interpersonal skills. Sonographers often work in fast-paced environments, juggling multiple patients and procedures throughout the day. Effective time management is essential to ensure that scans are performed efficiently without compromising quality. Adhering to schedules and meeting the demands of the healthcare facility can add to the workload and stress levels.
Salary Outlook:
The salary of a sonographer can vary, based on factors such as experience, specialization, geographic location, and work setting. According to the U.S. Bureau of Labor Statistics, as of May 2021, the median annual wage for diagnostic medical sonographers was $77,740. Sonographers working in specialized hospitals, outpatient care centers, and diagnostic imaging centers tend to earn higher salaries compared to those in physician offices or government facilities. The salary prospects for sonographers outside the United States can vary significantly based on factors such as the country's economic conditions, healthcare system, demand for sonographers, and cost of living.
Future Outlook:
The future outlook for sonographers appears highly favorable. The demand for ultrasound imaging continues to grow due to advancements in medical technology and an aging population. This increasing demand for sonographers is expected to result in good job prospects and potential career advancement opportunities. Monitoring job markets, understanding regulatory requirements, and networking with professionals in international healthcare communities can provide valuable insights into future opportunities.

Spatial Resolution
The spatial resolution describes the smallest distance between two points in the object that can be distinguished as separate details in the image, generally indicated as a length or a number of black and white line pairs per mm (lp/mm). In ultrasound imaging, the spatial resolution means how closely two reflecting tissues - or scattering regions, can be to one another while they can be identified as different reflectors.
Thyroid Ultrasound
A thyroid ultrasound evaluates the size and shape of the thyroid gland and parathyroid glands. A thyroid ultrasound can show nodules, cysts, tumors, and an enlargement, but a sonogram cannot determine the function of the thyroid. Ultrasound guides the placement of the needle during a thyroid fine needle aspiration biopsy.
