  2. 1. Internal Dosimetry Development and Evaluation of Methods and Models

    Author : Lena M Jönsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; crypt cells; intestine; radionuclide; scintillation camera; sestamibi; activity quantification; conjugate view method; Monte Carlo simulation; internal dosimetry; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; medicinsk instrumentering; radiologi;

    Abstract : Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. READ MORE

  4. 2. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy

    Author : Katarina Sjögreen Gleisner; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; 131-I; Clinical physics; SPECT; conjugate-view; volume quantification; activity quantification; image registration; image segmentation; medicinsk instrumentering; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

    Abstract : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. READ MORE

  5. 3. Activity quantification based on scintillation camera imaging - Application to 111In/90Y radioimmunotherapy

    Author : David Minarik; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radioimmunotherapy; bremsstrahlung imaging; activity quantification; SPECT; conjugate view; Yttrium;

    Abstract : Radionuclide therapy (RNT), is important for the treatment of certain benign and malignant diseases. 90Y-Zevalin™ therapy has become an established method of treating patients with non-Hodgkin B-cell lymphoma. READ MORE

  6. 4. A clinical positron emission tomography facility : 2-¹⁸FDG studies : development and results

    Author : Tomas G Ohlsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; head and neck cancer; monitoring therapy effect; quantification; normalization; 511 keV SPECT; rotating PET scanner; 2-[18-F]FDG; isotope production; 18-F; PET; positron emission tomography; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; Fysicumarkivet A:1996:Ohlsson;

    Abstract : Positron emission tomography (PET) is a tracer technique used for quantitative in vivo studies of physiological and biochemical processes. Because of the use of positron-emitting radionuclides such as 11-C, 13-N, 15-O and 18-F, which are isotopes of the biologically ubiquitous elements, it is possible to label radiopharmaceuticals which trace biochemical processes precisely.

  7. 5. Ventilation of the Paranasal Sinuses. A study using the 133-Xenon Washout Technique

    Author : Bo Paulsson; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; single photon emission computed tomography; paranasal sinuses; ventilation; 133-xenon; chronic sinusitis; nose-sinus model; endoscopic sinus surgery; oxymetazoline; Otorhinolaryngology; Otorinolaryngologi; audiologi; hörsel- och talorganen; audiology;

    Abstract : A noninvasive 133-xenon washout technique was used to evaluate the ventilation of the paranasal sinuses in healthy subjects and in patients with sinus disease. A mixture of air and 133-xenon is insufflated into the nasal cavities and passage into the sinuses is facilitated by a pressure increase created by letting the subjects inflate a balloon. READ MORE
