Characteristics of symptomatic men with testicular microlithiasis
M. R. V. Pedersen1, H. Møller2, S. Rafaelsen1, M. jørgensen1, P. Osther3, p. Vedsted4; 1Vejle/DK 2London/UK 3Fredericia/DK 4Aarhus/DK

Aims and objectives:
Testicular microlithiasis has been associated with carcinoma in situ and testicular cancer [1,2]. Risk factors for testicular cancer are not clear, but there are som acknowledged or suggested risk factors, e.g. chryptorchidism [3], height [4], familie history of testicular cancer [5] and mate[...]
Methods and materials:
A 23-item self-administered questionnaire was mailed to men who had undergone a scrotal ultrasound examination between 2004-2013 in the Department of Radiology. The men were categorized into men with testicular microlithiasis and men without, based on their previous ultrasound examination. The quest[...]
Results:
From the 1538 men who returned the questionnaire, a total of 197 men had testicular microlithiasis (12.8%). The mean age in men with testicular microlithiasis were 51.9 years (18-89 years) compared to 54.3 years (18-93) in men without. Overall, there were limted difference in men with and without t[...]
Conclusion:
Testicular microlithiasis was not associated with age, height or classic lifestyle factors such as alcohol consumption, smoking habits or mothers smoking during pregnancy. Men with testicular microlithiasis experienced less physical activity, and consumed more crisps than men without. Ingestion of c[...]

Testicular microlithiasis, ethnicity and socioeconomic status
M. R. V. Pedersen1, E. Bartlett2, S. Rafaelsen1, P. Osther3, p. Vedsted4, M. Sellars2, P. Sidhu2, H. Møller2; 1Vejle/DK 2London/UK 3Fredericia/DK 4Aarhus/DK

Aims and objectives:
Testicular microlithiasis is a common finding, characterized by bright minute calcifications (1-3 mm in diameter) placed in the lumen of the seminiferous tubules. There is no acoustic shadowing. The prevalence is around 6-18 % in adults [1-3]. The causes of testicular microlithiasis are unknown. [...]
Methods and materials:
We searched the PACS and CRIS system at the Department of Radiology King´s College Hospital, and found a total of 39961 scrotal examinations from 1998 to 2015 (search terms: calcification, microlithiasis, TM and TML). A total of 1105 patients with microlithiasis were identified, and a random coho[...]
Results:
Of the 1105 cases with TML a total of 423 (38,3%) were White, 273 (24,7%) Black, 152 (13,8%) other ethnicities, and 257 (23.2%) had no ethnicity recorded. In the control group of 1105 without TML at total of 560 (50,7%) were White, 171 (15,5%) Black, 111 (10,0%) other ethnicities and 263 (23,8%) had[...]
Conclusion:
The results implies that a possible variation in the underlying causes of testicular microlithiasis is associated with ethnicity.

Dual-energy CT of renal stones: a quantitative prediction of ESWL outcome
L. Meincke1, S. A. Minddal2, J. D. Nybing2; 1Copenhagen/DK 2Frederiksberg/DK

Aims and objectives:
The purpose of this study is to determine whether Dual-energy CT (DECT) can predict extracorporeal shockwave lithotripter (ESWL) outcome. The evaluation is based on a calculated CT-ratio (CTR) and ESWL-outcome. BACKGROUND: Renal stones or urinary calculi is a common disorder and remains a major ec[...]
Methods and materials:
The evaluation included nineteen patients who underwent DECT and subsequent an ESWL, over a three-month period (average age: 52 years, twenty-three renal stones). INCLUSION CRITERIA: a minimum of one renal stone diagnosed from the initial CT-scan. EXCLUSION CRITERIA: movements artefacts. JJ ste[...]
Results:
Comparing the two ESWL-outcome groups by CTR, this study found no significant difference between stones in the two groups (P>0.05), but 22% (2/9) with CTR < 1.30 and 43% (6/14) with CTR > 1.30 cannot be crushed (fragments). The Relative Risk (RR) = 1.94 indicates, that the renal stones in[...]
Conclusion:
This study shows a clear tendency suggesting that the DECT technique should be used to determine if each patient with urinary calculi is suitable for ESWL (CTR < 1.30 = suitable). This study should be repeated with a larger sample size.

Can pediatric radiography be practiced appropriately in non-dedicated pediatric radiology unit? Case study: A radiology department at a Norwegian local hospital
A. Rusandu1, E. Stranden2; 1Trondheim/NO 2Kongsberg/NO

Aims and objectives:
Norway’s population density, demographic scatter and distinct topography presents unique challenges for the medical system. One of them is the quite common practice at some small local hospitals to perform radiological examinations in children in the same unit as in adults despite international guid[...]
Methods and materials:
Case study analyzing the practice at a local hospital radiology department. The approach is qualitative, based on participant observation, document investigation and informal interviews with radiographers.
Results:
Common waiting areas and examination rooms for children and adults are used. Children are usually given priority in the queue. Communication with children seems to go well in most cases. Recommendations for CT examinations [3] such as early placing of intravenous line, explaining the process and sh[...]
Conclusion:
Despite variations in experience with children among radiographers and lack of specialization or training in pediatric radiography, the practice is largely in accordance with international recommendations. The requirements for radiation protection and optimization [1,2,3] are met even if the departm[...]

Fast direct-access for patients suspected for lower extremity deep vein thrombosis in general practice
A. Meyer Balle, A. Nielsen, p. Vedsted, C. Appel; Silkeborg/DK

Aims and objectives:
Lower extremity deep vein thrombosis (DVT) can lead to potentially life-threatening complications such as pulmonary embolism or trigger development of post-thrombotic syndrome (1,2). Accordingly, fast, early diagnosis and treatment are essential. Typically, patients present to general practice (GP[...]
Methods and materials:
All consecutive patients referred from GP to Diagnostic Centre, Silkeborg Regional Hospital, were followed in an observational study from 1 January 2016 – 31 December 2016. Data was extracted from the Radiology Information and Patient Administrative Systems, and mean salaries of healthcare professio[...]
Results:
Of 198 patients, GPs referred 144 (73%) patients through the yes-no strategy and 54 (27 %) via the follow-up strategy, and out of these patients 19 (13%) and 25 (46%) patients respectively were diagnosed with DVT (p<0.001). All patients had the whole-leg CUS performed on the day of referral. Th[...]
Conclusion:
We have shown that it is possible to organize direct-access to ultrasonography without pre-tests and using a sonographer for patients suspected for DVT. The new organization presents positive results in terms of shorter, more cost-effective pathways compared to the previous. To our knowledge, no oth[...]

Post-graduate course in interpreting and reporting skeletal images for radiographers in Norway, experiences from a collaboration project.
A. Myklebust1, A. Berntsen2, E. Kjelle1, K. G. Vikestad3; 1Kongsberg/NO 2Gjøvik/NO 3Lorenskog/NO

Learning objectives:
Learning objective: To facilitate radiographers’ post-graduate education in interpreting and reporting skeletal x-rays, by collaboration between three institution of higher education in Norway.
Background:
Changes in use of radiological procedures and continuous technological development are two factors increasing the pressure on radiologists and radiology [1]. Thus, there is a need for training radiographers in new skills in order to meet challenge in lack of radiologists. Studies conclude that advan[...]
Findings and procedure details:
A 45 ECTS post-graduated course are developed as a blended learning course. It is a combined course with online and on campus activities in addition to clinical training. Table 1,shows an overview of the three semester blended learning courses. Six post-graduate students has undergone the cour[...]
Conclusion:
Developing a groundbreaking course in collaboration causes different challenges. These challenges are, funding, organisation, collaboration culture, technology issues and lack of support from important groups like radiologists. However, experience from this project indicate that collaboration and fl[...]
