Modified X-ray procedures can be used to examine softer tissue, such as the lungs, blood vessels or the intestines. In this article, we'll find out exactly how X-rays machines pull off this incredible trick. As it turns out, the basic process is really very simple. Contents What's an...
LYMPHOSEEK® (technetium Tc 99m tilmanocept) injection is a radioactive diagnostic agent indicated with or without scintigraphic imaging for:Lymphatic mapping using a handheld gamma counter to locate lymph nodes draining a primary tumor site in adult and pediatric patients age one month and older ...
Ultrasonography was used for localization, which was performed by the department of endocrinology, or, alternatively, radiology, technetium 99m-sestamibi scintigraphy, computer tomography, and magnetic resonance imaging were used. Single imaging modality was used for 19 (52.7%) patients, while more ...
Physicians and patients around the world are increasingly anxious about the shortage of nuclear isotopes used in medical imaging. A single radionuclide--technetium-99m ([sup.99m]Tc)--is used in four-fifths of all such imaging procedures ... T Ruth - 《Nature》 被引量: 36发表: 2009年 ...
How is technetium-99m used in nuclear medicine? How can analog signals be converted to digital? How are signals made from images for cathode ray tubes? How does the electromagnetic force work? How does a basic analog voltmeter work? How does magnetism work? How does alternating current work?
Atoms: All of the elements that we know to exist are listed on the periodic table. If you notice, the atomic masses of each element are different, and they are generally decimal values. This value is the weighted average of each isotope for that element. ...
Molecular imaging is one of the pillars of precision surgery. Its applications range from early diagnostics to therapy planning, execution, and the accurate assessment of outcomes. In particular, molecular imaging solutions are in high demand in minimally invasive surgical strategies, such as the subst...

Such particles have a much higher LET than β particle emitters (50–230 keV/μm vs. 0.1–1.0 keV/μm) with an average energy deposition of 100 keV/μm. The range of α particles in tissues is short, which limits radiation deposition to the target cell and closely neighboring cells [...
particularly for a population in whom incidental findings are common. The aim of this review is to provide pictorial examples of benign musculoskeletal pathologies which may be found on molecular imaging and which may be mistaken for malignant processes. Imaging examples are provided in the form of...
