Dear Sir/Madam

we are grateful for visiting our website concerning the MWU DOBREUSG Diagnostic Centre. We are specialists in gyneacology and obstetrics focused mainly on medical ultrasound. For a few years we have been offering our help in consulting patients to the best OB/GYN specialists and their patients in Krakow. We also run a wide range of courses and workshops. We educate physicians from Poland as well as other countries. In 2011 we set up the MWU – Ultrasound Courses, which at present enable us to pursue our educational goals. During our courses we offer free-of-charge scans to women from Krakow and its surroundings. Our articles are published in prestigious medical journals, and our accomplishments are presented at World ISUOG Congresses. MWU DOBREUSG is the only in Lesser Poland private wide-scope consulting and diagnostic centre of congenital defects as well as ultrasound diagnosis in gynecology and gynecologic oncology.

What makes us unique:

  • Individual approach to each patient – at our centre you will be treated with understanding and approval in a friendly atmosphere created during the scan.
  • Objectivity – we always have in mind our patients’ mental comfort. We do not frighten you without a reason! We do not frighten young women after 35 years of age! We explain all diagnosed anomalies in a comprehensible way, and together with the best OB/GYN physicians in Krakow, we provide further treatment.
  • Professionalism – all our specialists are highly skilled, which is confirmed by adequate certificates. We work in a team and support one another in every situation.
  • Full diagnostics – we offer not only based on ultrasound scans. We take blood samples for NIPT (Neobona/Harmony/NIFTY) – non-invasive screening tests of high sensitivity for most common genetic syndromes. Also, chorionic villus sampling, amniocentesis and fetal blood sampling are performed at our centre. We cooperate with well-known specialists in pediatric areas and genetics.
  • Passion – we are passionate about what we do!

We wish you a pleasant reading and invite you to visit us!

What we do


Medical ultrasound

We deal with comprehensive ultrasound diagnostics in obstetrics and gynecology. We are the only private centre consulting congenital defects in a fetus in cooperation with specialists in the following fields of pediatrics: cardiac surgery of congenital heart defects, neurosurgery, pediatric neurology, pediatric urology, and clinical genetics, among others. Also, in cooperation with onco-gynecologists, we carry out ultrasound consultations of difficult cases, mainly suspected of cancer. We are ultrasound specialists of international renown in the field of obstetrics and gynecology. Dr. Marcin Wiechec  and Dr. Nocun are the only in Poland International Faculty Members of the International Society of Ultrasound in Obstetrics and Gynecology (ISUOG). We cooperate with the Polish Ultrasound Society and Dr. Nocun is an examiner in this institution.


Fetal heart 3D models and Virtual Reality for Congenital Heart Diseases

We introduced 3D models of a normal fetal heart and a wide range of models presenting most common fetal heart defects into the education of specialists and students of medicine as well as into the consultations of our patients. Our models are employed not only in Poland during our ultrasound courses, but also in the United Kingdom, Germany, Romania, Bulgaria, South Africa, Azerbaijan and the Netherlands. Recently we have extended this project to the Virtual Reality (VR) application simulating a fetal cardiac scan of a normal and abnormal heart.  It is aimed at better preparation of physician for cases of Congenital Heart Diseases.


Research in Medical Ultrasound

We are not only reliable specialists in our field, but we also conduct a scientific research, which aims to improve ultrasound diagnostic performance in obstetrics and gynecology. For instance, we are the first to study ultrasound diagnostic performance based on a lot of parameters in order to detect the Down syndrome, the Edwards’ syndrome and the Turner syndrome; we also described the coincidence of ultrasound markers for most common genetic syndromes; in addition, we compared the performance of a standard strategy in the first trimester offered in centres which have a contract with the National Health Fund with an ultrasound strategy offered by us; we also worked up most common models of fetal heart defects in the first trimester, moreover, we described a method of examination towards the agenesis of corpus callosum, we analyzed methods of the assessment of endometrial carcer inavasion and proposed our own method. The results of our research are presented at international congresses as well as during courses conducted at our school of ultrasound. Read more
