Implementation of new technologies in medicine is historically connected via a collaboration between physicians and physicists. Through many of the new medicine methods were famously in the spotlight, the technology and physics remained hidden in the background. Interestingly. it is true that at the outset many of these new technologies were implemented into medical practice without any proper study of its physical basis, risk assessment or appropriate research (an example of this is radiotherapeutics use of X-rays within 6 months after their discovery). Current state-of-the-art of medicine requires a close cooperation between physicians and clinician technologists, and in the case of the use of ionizing radiation, also medical physicists. Correct cooperation is the basis of up-to-date medical care, which now more than ever before, is a multidisciplinary branch., Pavel Solný., and Obsahuje bibliografii
Radiologické metody a postupy se staly neodmyslitelnou součástí screeningu, diagnostiky, terapie a managementu onemocnění pacientů s kolorektálním karcinomem. Do popředí zájmu se dostávají CT kolonografie (virtuální kolonoskopie) v rámci screeningu, metody kontrastního ultrazvuku ke zrychlení diagnostického postupu a magnetická rezonance zejména v precizní diagnostice jaterního postižení a lokálního stagingu karcinomu rekta. V posledním desetiletí se etablovaly radiologické intervenční metody určené pro ty nemocné, u kterých standardní řešení selhává. Intervenční radiologie tak rozšiřuje možnosti léčby u pacientů s diseminovaným kolorektálním karcinomem (ve stadiu IV). Terapeutické invazivní metody při terapii metastatického postižení jater mohou být buď intravaskulární (chemoembolizace a regionální chemoterapie, předoperační embolizace portální žíly), nebo perkutánní (především radiofrekvenční termoablace). Tyto metody je možné využít jak v rámci downstagingu onemocnění se záměrem umožnění kurativní resekce, tak v rámci paliace onemocnění., Radiological methods and procedures have become an inseparable part of the screening, diagnosis, therapy and disease management of patients with colorectal cancer. Major areas of interest are CT colonography (virtual colonoscopy) during screening, contrast-enhanced ultrasound in speeding up diagnostic procedures and magnetic resonance imaging, especially in the precise diagnosis of liver disease and local staging of rectal cancer. Radiological interventional methods have been more established in the last decade, as they are suitable for those patients where a standard solution fails. Interventional radiology extends the treatment options for patients with disseminated colorectal cancer (at stage IV). Invasive therapeutic methods in the treatment of liver metastases can be either intravascular (chemoembolization and regional chemotherapy, preoperative portal vein embolization) or percutaneous (particularly radiofrequency thermoablation). These methods can be used within downstaging of disease to allow curative resection, as well as in palliation of the disease., Tomáš Andrašina, Vlastimil Válek, Igor Kiss, Aleš Neumann, and Lit.: 21
