All the patients underwent magnetic resonance imaging or computed tomography simulation scans. Treatment planning techniques used for each patient were three-dimensional conformal radiotherapy and intensity-modulated radiotherapy. After evaluating patterns, a better plan and treatment with an X-ray beam was chosen. Data was analysed using SPSS 24.\r\nResults: The study involved thirty participants, with 17(57%) females and 13(43%) males, aged 19-45, and 28 patients having chemotherapy. Six out of thirty had craniotomy surgery. The intensity-modulated radiation therapy had a safer radiation dose than the three-dimensional conformal radiotherapy for spinal cord (p=0.3203), brain stem (p= 0.17924), right parotid gland (p=0.8556) and left parotid gland (p=0.2193). The three-dimensional conformal radiotherapy protected the organs better than intensity-modulated radiation therapy for left optic nerve (p=0.1227), right optic nerve (p=0.0032), left eye (p=0.3859), right eye (p=0.1189), left lens (p=0.0004), right lens (p=0.0001), optic chiasm (p=0.0320) and pituitary gland (p=0.9162).\r\nConclusion: The intensity-modulated radiation therapy technique protected the spinal cord, brain stem, and right and left parotid glands. The three-dimensional conformal radiotherapy was safe for left and right optic nerves, left and right eyes, left and right lenses, optic chiasm and pituitary glands.\r\nKey Words: Radiotherapy, Parotid Gland, Optic Chiasm, X-Rays, Pituitary Gland, Radiation, Spinal Cord, Brain Stem, Craniotomy, Tomography<\/jats:p>","DOI":"10.47391\/jpma-bagh-16-68","type":"journal-article","created":{"date-parts":[[2024,10,8]],"date-time":"2024-10-08T14:14:19Z","timestamp":1728396859000},"page":"S298-S301","source":"Crossref","is-referenced-by-count":2,"title":["An efficacy of protection the organs at risks comparison between the intensitymodulated radiotherapy therapy (IMRT) and the three-dimensional conformal radiotherapy (3DCRT)"],"prefix":"10.47391","volume":"74","author":[{"family":"Abd Al-Taj Abd Ali Khaleel","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Siham Sabah Abdullah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Sabbar Shukri Al-Bayaty","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Abdulrahman Mohammed Abdulbaqi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"family":"Nabaa Mohammad Ali Alazawy","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"26547","published-online":{"date-parts":[[2024,9,28]]},"container-title":["Journal of the Pakistan Medical Association"],"original-title":[],"link":[{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/21891\/3733","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/download\/21891\/3733","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,10,11]],"date-time":"2024-10-11T14:14:19Z","timestamp":1728656059000},"score":1,"resource":{"primary":{"URL":"https:\/\/jpma.org.pk\/index.php\/public_html\/article\/view\/21891"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,9,28]]},"references-count":0,"journal-issue":{"issue":"10 (Supple-08)","published-online":{"date-parts":[[2024,9,28]]}},"URL":"https:\/\/doi.org\/10.47391\/jpma-bagh-16-68","relation":{},"ISSN":["0030-9982","0030-9982"],"issn-type":[{"value":"0030-9982","type":"electronic"},{"value":"0030-9982","type":"print"}],"subject":[],"published":{"date-parts":[[2024,9,28]]}}}
