12. Imaging of small amounts of pleural fluid. Part one - small pleural effusionsIgor Kocijančič, 2005, pregledni znanstveni članek Povzetek: Background. Small pleural effusions are not readily identified on conventionalradiographic views of the chest, but may be an important finding, sometimes leading, via thoracocentesis, to a definitive diagnosis of pleural carcinomatosis, infection or transudate. A small meniscus sign and a medial displacement of the costophrenic angle are the only subtle signs of small accumulations of fluid on posteroanterior chest X-rays. On lateral views the finding of a small meniscus sign in the posterior costophrenic angle is the sign of small pleural effusion. Conclusions. Lateral decubitus chest radiographs were used for many years for the diagnosis of small pleural effusions. In last decades ultrasonography of pleural space becomes a leading real-time method for demonstrating small pleural effusions.

13. Sonography of pleural space in healthy pregnants - preliminary resultsIgor Kocijančič, 2005, izvirni znanstveni članek Povzetek: Background. The purpose of our study was to determine the incidence of sonographically visible normal pleural fluid finding in healthy pregnants. Methods. Chest sonography was performed in 47 pregnant volunteers, searching for pleural fluid, first leaning on the elbow and than in a sitting position. 9-12 MHz linear probe was used. If the result of the first examination was positive (at least 2 mm thick anechoic layer), we repeated the procedure with 3-6 MHz large radius convex probe. Results. The fluid layer of typical wedge-shaped appearance was visible in the pleural space of 28/47 (59.5%) pregnant volunteers, on both sides in 18/47 (38.3%) and unilaterally in 10/47 (21.2%). The mean fhickness of fluid layer (mean of positive results in both positions) was 2.86 mm (SD 1.09 mm, range from 1.8 mm to 6.4 mm). More than 3 mm thick fluid layer was easily detected with 3-6 MHz abdominal convex probe in 7/47 (15%). Conclusions. Small amounts of pleural fluid can sometimes be detected by chest sonography, and hence also by abdominal sonography, in otherwise healthy pregnants. Such a positive result, if isolated, should not be taken as a sign of occult thoracic disease.

14. Sonographically guided fine-needle aspiration biopsies of adrenal masses in lung cancer patients, eleven-year experienceIgor Kocijančič, 2004, izvirni znanstveni članek Povzetek: Purpose. The aim of this retrospective study was to define the accuracy and safety of the ultrasonographically (US) guided fine-needle aspiration biopsy (FNAB) of the enlarged adrenals in the patients with lung cancer. Patients andmethods. In eleven-year period 64 patients with cytologically proven lung cancer underwent USguided FNABs of adrenal masses. The accuracy of the method was assessed on the basis of cytology findings and the safety on the number ofcomplications reported after the procedure. Results. US-guided aspiration biopsy turned out to be accurate in 58/64 cases (91%), and very safe with only4/64 (6%) minor complications. In 52/58 (90%) cases, the cytology sample was found to be malignant. In 6 cases (10%), isolated adrenal masses were adenomas. Conclnsions. We recommend US guided FNAB as a safe and reliable diagnostic method that has many advantages over computer tomography (CT) guided FNAB, such as safety, patient friendliness, no X-rays and its reproducibility.

15. The accuracy of chest sonography in the diagnosis of small pleural effusionIgor Kocijančič, 2003, izvirni znanstveni članek Povzetek: Background. The aim of the stndy was to evaluate the accuracy of chest sonography in the radiological diagnosis of small pleural effusions. Patients and methods. Patients referred for abdominal and/or chest sonographies for various reasons were examined for sonographic features of pleural effusion. From January 1997 till January 2000, 69 patients were included into the study.Fifty-two patients were found to have pleural effusion not exceeding 15 mm in depth, the rest of them served as controls. Subsequently erect posteroanterior and expiratory lateral decubitus projections were done in all patients. Results. Compared to radiologicai examination chest sonography had apositive predictive value of 92% in the diagnosis of small pleural effusions in our study population. The mean thickness of fluid was 9.2 mrn on ultrasonography and 7.6 mm on expiratory lateral decubitus views (P<0.01). Conclusions. Chest sonography showed a high degree of accuracy for demonstrating small pleural effusions and could repIace lateral decubitus chest radiographs adequately.

16. How reliable is classic chest radiography in the diagnosis of small pleural effusionIgor Kocijančič, Ksenija Kocijančič, 1999, izvirni znanstveni članek Povzetek: Purpose. To evaluate the usefulness of expirium lateral decubitus views in theradiological diagnosis of small pleural effusions. Materials and methods. Patients referred to abdominal sonography for different reasons were routinelychecked for possible pleural effusion. From November 1994 till May 1996, 36 such patients were found to have pleural effusion not exceeding 15 mmand were included in the study. Patients were examined radiologically in erect PA and lateral projections and, after 5 min. in decubitus position, in inspiratory-expiratory lateral decubitus projections with 10 hip elevation andcentral beam on the lateral chest wall. Results. In 22 out of 36 patients (61 %), the pleural fluid was not visible on erect PA and lateral chest radiogram. However, the fluid was visible in 35/36 patients (97%) in expirium from lateral decubitus view. The average thickness of fluid from lateral decubitus views in inspirium and expirium was 4.3 and 7.9 mm, respectively. In31 out of 36 patients (86%), the thickness of the fluid layer as measured inexpirium and inspirium was different. In 16%, the fluid was not visible on inspirium lateral decubitus projections. Conclusions. Radiography turned out to be almost as sensitive as sonography in detection of small pleural effusions. Lateral decubitus views taken in expirium contributed essentially to the diagnostic sensitivity in our study.

17. Najpogostejše bolezni dojk in njihove mamografske značilnostiBreda Jančar, Igor Kocijančič, 2001, objavljeni znanstveni prispevek na konferenci Povzetek: Radiološki inženir, ki se ukvarja z mamografsko diagnostiko, potrebuje osnovnoznanje o boleznih dojk. To je zlasti pomembno pri dodatnih slikovnih diagnostičnih postopkih, ki zahtevajo timski pristop. Zato so v sestavku na kratko opisane najpogostejše bolezni dojk s poudarkom na njihovih mamografskihznačilnostih.

18. Asimetrije dojk, strukturni nemir in zvezdaste lezijeIgor Kocijančič, Miljeva Rener, 1998, pregledni znanstveni članek Povzetek: Opisali smo mamografske značilnosti diferencialno diagnozo in dodatne diagnostične postopke pei mamografskih najdbah strukturnega nemira, asimetrij in zvezdastih lezij. Nakazali smo na korelacijo med kliničnimi in mamografskimi najdbami. Možnost malignoma je najmanjša pri asimetrijah, večja pri strukturnih lezijah v kombinaciji z asimetrijo in največja pri zvezdastih lezijah.
