    Aim: To investigate final year undergraduate radiography students' perceptions of clinical placements, in relation to the clinical learning environment (CLE) and their learning achievements.
    Methods: A 19-item pre-coded questionnaire with five point Likert-scale responses was administered face-to-face to 24 of the 27 final year radiography students who undertook mandatory clinical placements. Purposive sampling method was used to recruit participants. The Statistical Package for the Social Sciences (SPSS) version 21.0 was used to process the descriptive statistics data for analyses.
    Results: The clinical placement enhanced students' skills in patient-centred care, interpersonal and clinical competence. Placement afforded students opportunity to put theoretical knowledge acquired in the class- room into real practice. Students' rated the assistance of practising radiographers as appropriate for achieving learning outcomes and satisfaction. Radiographers gave adequate supervision and actively included students in clinical activities as team members. Also, there were adequate learning resources at placement sites. However, the students reported that they received inadequate feedback on their clinical performances and seminars organized were not enough.
    Conclusion: The students rated their clinical learning environment as positive and supportive, and achieved various clinical skills with satisfaction from clinical placements. Nevertheless, the students' articulated of been denied performance feedback by supervisors, of which the students were unhappy about.

    Objective: Stereotactic radiosurgery (SRS) is an innovative approach for cancer therapy. It is thought to be generally a good choice even to radioresistent brain metastases (BM), taking also into consideration all of the prognostic factors and co-morbidities. But until now, it has not been revealed whether the apparatus is linked to the outcome.
    Methods: Because of that, the authors searched the published data on the world search engine for the last decades (1947-2017) on the subject of renal and lung cancer brain metastases (BM) and their radosurgical therapy, in regard to the used apparatus.
    Results: After processing the published data, the authors revealed that the three kinds of machines are leading to different results, concerning the brain metastases. LINAC and CyberKnife seem to be linked to the outcome, mainly to the local control/local failure, while GK’s analysis revealed no actual connection. Overall survival in general could be linked also to the machine, but it depends on many factors and such relation is difficult to be clearly determined.
    Conclusion: Concluding to this, it becomes clear that GammaKnife, CyberKnife and LINAC are not the same for the therapy of BM from primary lung and renal cancer. And before proceeding with SRS, it should be considered which machine would be used for the therapy, in order for a better outcome to be achieved.
