Available in PDF, EPUB and Kindle. Book excerpt: This report describes approaches to calculating and expressing radiation doses to the embryo/fetus from internal radionuclides. Information was obtained for selected, occupationally significant radioelements that provide a spectrum of metabolic and dosimetric characteristics. Evaluations are also presented for inhaled inert gases and for selected radiopharmaceuticals. Fractional placental transfer and/or ratios of concentration in the embryo/fetus to that in the woman were calculated for these materials. The ratios were integrated with data from biokinetic transfer models to estimate radioactivity levels in the embryo/fetus as a function of stage of pregnancy and time after entry into the transfer compartment or blood of the pregnant woman. These results are given as tables of deposition and retention in the embryo/fetus as a function of gestational age at exposure and elapsed time following exposure. Methodologies described by MIRD were extended to formalize and describe details for calculating radiation absorbed doses to the embryo/fetus. Calculations were performed using a model situation that assumed a single injection of 1[mu]Ci into a woman's blood; independent calculations were performed for administration at successive months of pregnancy. Gestational -stage-dependent dosimetric tabulations are given together with tables of correlations and relationships. Generalized surrogate dose factors and categorizations are provided in the report to provide for use in operational radiological protection situations. These approaches to calculation yield radiation absorbed doses that can be converted to dose equivalent by multiplication by quality factor. Dose equivalent is the most common quantity for stating prenatal dose limits in the United States and is appropriate for the types of effect that are usually associated with prenatal exposure. If it is desired to obtain alternatives for other purposes, this value can be multiplied by appropriate weighting factors.

This book was released on 1985 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: The editors address the anxiety-provoking, but not uncommon, scenario of a woman learning that she is pregnant after diagnostic or therapeutic radiologic exposure, or alternately, requiring X-rays, magnetic resonance, radioisotopes, or ultrasound after she becomes pregnant. Considerations span: the mechanisms for injury by diagnostic radiations, the units and measures of radiation, the amount of radiation absorbed by the conceptus, prenatal risk assessment, clinical management, and case reports (of diseases and traumatic injuries) exemplifying decision recommendations and counseling. Appendixes guide conceptus dose calculations for X-ray exams and radionuclide studies, and list half-lives of 23 radionuclides used in nuclear medicine (5,730 years for Carbon-14).

This book was released on 2019-12-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whenever a diagnostic or interventional X-ray examination of a pregnant patient is considered to be necessary, conceptus dose estimation is an essential step in assessing the radiogenic risks to the unborn child. Accurate estimation of embryo/fetus radiation dose is also needed after accidental exposure of a pregnant patient from an X-ray procedure. The exposure of pregnant patients to medical X-rays is often a complex case and involves emotionally sensitive issues for both prospective parents and physicians. Conceptus dose assessment is not always easy. Medical physicists should be able to assess conceptus doses and risks from diagnostic and interventional procedures and also to place the risk in a perspective from which an informed decision can be made. Pregnant medical professionals working with radiation have many misconceptions about the risks of ionizing radiation on the unborn child. Medical radiation workers of childbearing age should be aware that careful planning and dose optimization of examinations can address their concerns and permit, in the vast majority of cases, safe performance of procedures. Pediatric patients requiring diagnostic and interventional procedures are exposed to diagnostic and interventional X-rays. Pediatric patients are more sensitive to radiation than adults and, for this reason, accurate assessment of doses and risks is needed in these cases. Medical physicists should be able to assess paediatric doses and risks from diagnostic and interventional procedures. Several techniques and tools have been developed for dose optimization of radiographic, fluoroscopic, computed tomography and fluoroscopically-guided interventional pediatric procedures. The scan parameters should be adjusted for patient size and body region. Part of Series in Physics and Engineering in Medicine and Biology.

Available in PDF, EPUB and Kindle. Book excerpt: An intuitive, ingenious and powerful technique, sentinel lymph node biopsy has entered clinical practice with astonishing rapidity and now represents a new standard of care for melanoma and breast cancer patients, while showing great promise for the treatment of urologic, colorectal, gynecologic, and head and neck cancers. This text, written by international experts in the technique, provides a clear and comprehensive guide, presenting a detailed overview and discussing the various mapping techniques available and how these are applied in a number of leading institutions. This essential resource for surgical onocologists, pathologists, and specialists in nuclear medicine will also provide key information for those planning to start a sentinel lymph node program.

Scientific Committee 4-4 on the Risks of Ionizing Radiation to the Developing Embryo, Fetus, and Nursing Infant and published by National Council of Teachers of English. This book was released on 2013-01-01 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: NCRP Report No. 174, Preconception and Prenatal Radiation Exposure: Health Effects and Protective Guidance, updates and expands the National Council on Radiation Protection and Measurements (NCRP) Report No. 54, Medical Radiation Exposure of Pregnant and Potentially Pregnant Women (1977). Scientific knowledge has increased and public concerns have changed in the 36 y since NCRP Report No. 54 was published. The scope of NCRP Report No. 174 covers both ionizing radiation sources and specific nonionizing sources [i.e., magnetic-resonance imaging (MRI), ultrasound imaging, and radiofrequency (RF) fields]. This Report provides information on the types, sources and magnitudes of ionizing radiation exposures of reproductive relevance. Ionizing radiation exposures from medical care (diagnostic and therapeutic procedures, including radiopharmaceuticals) are addressed as well as from occupational sources, common environmental exposures, and from accidental or deliberate (e.g., a terrorist act) releases of radionuclides. The ionizing radiation sources discussed consist predominantly of low linear energy transfer (LET) radiation (e.g., x rays from prenatal medical procedures). The risks from ionizing radiation exposure are examined in detail from preconception through pregnancy, and during the nursing of infants. Outcomes and associated risks from preconception exposure that were evaluated include: infertility, stillbirths, birth defects, genetic alteration, and cancer. Outcomes and associated risks from exposure during pregnancy that were evaluated include: congenital malformations, growth retardation, embryonic and fetal death, mental retardation and neurobiological effects, and cancer. Also discussed is the risk to the nursing infant from the transfer of radioactive material through the mother's milk (e.g., milk from a mother who received a radiopharmaceutical) as well as from direct exposure due to radionuclides present in the mother's body.
