X-ray positioning in several projections facilitates the localisation of tachycardia with an accuracy of 4-8 cm2. From eight cadaver hearts schematic diagrams of the right ventricle for two dimensional echocardiography were derived. Endocardiac ventriculocartography under sonographic control was applied in 27 patients 45 times. With this method we were able to detect the electrode catheter in 42 of 45 (93%) patients effectively. Sonographic control facilitates not only the localisation of tachycardia without radiation burden but also its correlation with anatomic ventricular structure which is not possible by roentgenology. 3 negative results were due to negative echoes. In 3 of 5 cases the fulguration of the ventricular tachycardia focus under echo control was possible. Sonographic check up therefore is predilection method for endocardiac ventricular cardiography and can be recommended.</p>","PeriodicalId":20972,"journal":{"name":"Radiologia diagnostica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1990-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13389191","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Diagnostics imaging meanwhile has become the turning point of tumour detection at a prognostically favourable stage. Mammography is the recognized method for the diagnostics of breast disease.

Here sonography is used for differentiation of cystic and solid space occupations. With fine needle biopsy a preoperative dignity evaluation is more and more possible. Radiation planning becomes more effective. Computed tomography is more important for primary diagnostics and the spreading of the disease.

The variation is less than 5% for tube voltages between 55 and 120 kV (Exposure control system Robotron type 20041). Variations of film density connected with changes of focal spot size are explained by changes of kVp (insufficient tube load compensation) and by differences of energy sensitivity of ionization chambers and screen-film combinations as well as differences in exposure time for different focal sizes.
