StructureDisappeared Jugular Vein Showed
StructureDisappeared, jugular vein showed clear, high density and uniform was a shadow of seriousWith cervical and lowdensity condylar gap between the disappearance. This group of stem density within the soft tissue thickening41 cases, accounting for 59.4. Research reports NPC before radiotherapy of soft tissue invasion and when the stalks by radiotherapyStem density within the soft tissue thickening was slightly reduced
Compared with a preradiotherapy, but recovery slow, some casesHas not fully recovered and easily at the site recurrence; and soft tissue within the stem before radiotherapyWhen not involved, its occurrence after radiotherapy are less likely to change. Therefore, when designing a field before radiotherapyMust pay attention to whether they are invaded.Some scholars would be violations of the nasal cavity is
Divided into two types of NPC, one for the free passing a type (EP), On behalf of nasopharyngeal tumor free margin of exogenous forward broke into the nasal cavity, nasal mucosa;Another model for mucosal invasion (MI), on behalf of nasopharyngeal tumor invasion to the nasal mucosa, is usually consideredIn the latter type is the real violation of the nasal cavity,
