Medications as well as Blood work services also included with delivery even with drones to remote locations and on long weekends and holidays. diagnostic testing for colon cancer screening (non-invasive) with cologuard for those 50 years or older done as well. It has so many advantages over conventional colonoscopy as it is done at home, no procedure-associated risks such as perforation, bleeding needing surgery or blood transfusion, no special prep, do not have to take time off work with high accuracy up to 92% of colon cancer and can detect 69% of pre-cancerous lesions. It is FDA approved to test Stool DNA for colon cancer. All related educational material and Videos are also available for sale. Similarly, Diabetes monitoring supplies, blood pressure monitoring and related educational material. Diagnostic Imaging with CT scan or MRI or Ultrasound study is available.
Basics of Radiation Interactions in Matter
Published in Michael Ljungberg, Handbook of Nuclear Medicine and Molecular Imaging for Physicists, 2022
Most applications in nuclear medicine depend to some extent on the physics behind interactions between charged particles and the surrounding material or between electromagnetic radiation (photons) and charged particles, whether it is for radionuclide therapy, diagnostic imaging, or simply radiation detection. Solid knowledge of the underlying processes by which radiation interacts with matter is, therefore, of utmost importance in order to fully understand the potential and, more importantly, the limitations and risks for patients and personnel associated with the use of radiation.
Medical and Biological Applications of Low Energy Accelerators

PET is a diagnostic imaging procedure used regularly to acquire essential clinical information. The PET-CT hybrid, which consists of two scanning machines: PET scanner and an X-ray CT. At present, these represent the technological hierarchy of Nuclear Medicine, occupying an important position in diagnostics. In fact, PET-CT has the capability to evaluate diseases through a simultaneous functional and morphostructural analysis. This allows for an earlier diagnosis of the disease state, which is crucial for obtaining the required information to provide a more reliable prognosis and therapy. Presently, the most frequently used PET radiotracer fluorodeoxyglucose (18FDG) has a major role in oncology. Useful information is being regularly obtained by using both 18FDG and a selection of radiotracer compounds to evaluate some of the most important biological processes (Kitson et al. 2009).
Development of a navigable 3D virtual model of temporal bone anatomy

A CT or CAT (Computer Axial Tomography) scan, is a non-invasive diagnostic imaging test which uses modified x-ray technology to generate cross-sectional images of the body or a body part from different positions. It involves selective exposure of the patient to radiation. This data is then used to create detailed images of internal organs, bones, soft tissues, and blood vessels. CT scans help identify any tumours, blood clots, fractures, or other abnormalities that are indicative of trauma or any underlying pathology. A narrow X-ray beam circles around and selectively penetrates the part of the body being inspected. Instead of a film, the X-rays are picked up by special detectors, that are located directly opposite to the x-ray source, and transmitted to a computer (Brennan 2010). The computer uses sophisticated mathematical algorithms to assemble 2D cross-sectional images or slices. Recent growth in software technology has enabled us to easily construct 3D volumes from 2D CT images. 3D CT allows simultaneous navigation in all three planes, thereby providing greater flexibility than conventional planar X-rays (Fatterpekar et al. 2006). It is currently used in areas such as trauma, tumours, and craniofacial deformities, to simulate the morphology of body parts.

Pregnant patient, and fetal exposure, to ionizing radiation may be necessary to address urgent maternal health conditions, or may at other times be unintentional, such as when the woman does not yet know she is pregnant; both diagnostic and therapeutic radiographic procedures may be involved. In 1982, Mossman and Hill (Mossman and Hill 1982) found that approximately one percent of women were exposed to abdominal or pelvic radiation imaging, most often in the first trimester before being aware of pregnancy. When it does occur, radiation exposure of the pregnant or possibly pregnant patient is one of the most contentious issues that radiologists, radiologic technologists and clinicians face in communicating with anxious families and patients (International Commission on Radiological Protection (ICRP) 2000; National Council on Radiation Protection and Measurements (NCRP) 2013). Planned diagnostic imaging exposures of pregnant patients address the clinical conditions for which pregnant women are at risk (e.g., trauma, pulmonary thromboembolism, stroke, arteriovenous malformations, urinary stone, appendicitis). One in one-thousand pregnant women have a new cancer diagnosis — with the most common cancer being breast cancer — and these women may need staging imaging as well as radiotherapy. Women are also accidentally exposed from procedures using ionizing radiation — most commonly after trauma - including radiotherapy, interventional procedures, diagnostic procedures and nuclear medicine imaging.

With more than 35,000 systems currently in use worldwide, magnetic resonance imaging (MRI) is one of the most flexible tools in medical research and diagnostic imaging [1]. Thanks to superior soft-tissue contrast and non-ionizing radiation hazard, MRI applications in medical diagnosis are continuously growing. MRI needs a strong static magnetic field associated with gradients and radiofrequency (RF) pulses for image production [2]: the static magnetic field is permanently present while gradients and RF pulses are only activated during the MRI scan execution. These gradients and RF pulses are also more confined in the MRI scanner bore while the static magnetic field is constantly present inside and around the MRI facility: its value is a maximum in the scanner isocenter and decreases quickly moving away from the scanner bore. MRI staff (e.g., technicians, radiologists, anesthetists, anesthesiologists, researchers, maintenance, cleaning operators, etc.) are not usually exposed to gradients and RF fields, unless the worker remains in the scanner room during scanning [3,4].
