from organs. Machines that combine the PET and CT images, called a PET/CT, are  commonly used 5. Ultrasound Diagnostic medical sonography is a noninvasive procedure that is considered very  safe for the patient. Sonography is used extensively for fetal imaging. This imaging  modality, often referred to as diagnostic ultrasound, uses high-frequency sound  waves to produce echoes in the body. As the echoes return to the hand-held  transducer, their strength and timing are interpreted by a computer to produce a  map or graphic image of the echo distribution. Special transducer probes can be  inserted into body cavities (e.g., the rectum and the vagina) to obtain more detailed  examinations of the prostate gland and the uterus. Any interface between  substances or tissues of varying density produces an ultrasound echo, which makes sonography an effective technique for showing the shape, size, and condition of  organs such as the heart, spleen, gallbladder, breast, and pancreas (Figure 43-22).  Sonography, therefore, can be used to diagnose or investigate gallstones or  suspicious masses in the breast.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
