PROPOSITIONS

belonging to the thesis

CT COLONOGRAPHY IN FAECAL OCCULT BLOOD TEST POSITIVES

by M.H. Liedenbaum

1. CT colonography has a performance equal to that of colonoscopy for the detection of lesions larger than 10 mm in people with a positive faecal occult blood test

result. this thesis

-2. CT colonography is not well suited to use as a triage method in the first round of faecal occult blood test screening because of the high prevalence of lesions in this

population. this thesis

-3. The bowel preparation for CT colonography can be limited to the intake of an

iodine based contrast agent for a single day. this thesis

-4. The radiation dose used for CT colonography can be reduced to a dose which is comparable with the annual background radiation. Unfortunately many

institutions use a higher dose. this thesis

-5. Novice CT colonography readers obtain a sensitivity for polyp detection equal to that of an experienced reader after practising an average of 164 CT

colonographies. - this thesis

-6. Better student selection regarding professional behaviour should take place during the study of medicine so that the number of ‘rude’ doctors might decrease. 7. It is safer in a chemical plant than in a hospital. - R. Willems, Shell - 8. A strange folklore: While women abroad experience a painless childbirth in

hospitals, we put the bed on blocks, cook pans of hot water and, in a very mediaeval manner, midwives appear. - Herman Pleij - 9. Finishing a thesis is like running a marathon; hard times are experienced and it

demands perseverance but there are also moments of victory.

10. Strength does not come from physical capacity. It comes from an indomitable

will. - Mahatma Gandhi -

behorend bij het proefschrift

CT COLONOGRAPHY IN FAECAL OCCULT BLOOD TEST POSITIVES

door M.H. Liedenbaum

1. CT-colografie is net zo goed als coloscopie in het detecteren van laesies groter dan 10 mm in mensen met een positieve uitslag van de test op fecaal occult

bloed. dit proefschrift

-2. CT-colografie kan beter niet als triagemethode worden gebruikt in een eerste ronde van screening met een test op fecaal occult bloed, vanwege de hoge prevalentie van afwijkingen in deze populatie. dit proefschrift

-3. De darmvoorbereiding voor CT-colografie kan worden beperkt tot slechts een dag inname van een contrastmiddel op basis van oraal jodium. dit proefschrift -4. De stralingsdosis voor CT-colografie kan worden beperkt tot een dosis die

vergelijkbaar is met de jaarlijkse achtergrondstraling. Helaas gebruiken nog veel

instituten een hogere dosis. - dit proefschrift -

5. Onervaren CT-colografiebeoordelaars bereiken na gemiddeld 164 CT-colografieën een sensitiviteit voor poliepdetectie die vergelijkbaar is met die van ervaren

beoordelaars. - dit proefschrift -

6. Tijdens de geneeskundestudie moet een betere selectie plaatsvinden onder toekomstige artsen op professioneel gedrag, zodat het aantal ‘lompe’ dokters verminderd wordt.

7. In een chemische fabriek is het veiliger dan in een ziekenhuis. - R. Willems, Shell - 8. Een curieuze folklore. Waar vrouwen elders pijnloos in het ziekenhuis bevallen,

zetten wij het bed op klossen, rukken pannen met kokend water aan en duiken, heel middeleeuws, de vroedvrouwen op. - Herman Pleij -

9. Promotieonderzoek doen is net een marathon lopen; het vereist een enorm doorzettingsvermogen en er zijn momenten van afzien, maar ook van overwinning.

10. Strength does not come from physical capacity. It comes from an indomitable

will. Mahatma Gandhi
