Alex,
you need to review the definition of the 
Patient root model

more importantly look at the FAQ #38 on dcmtk forum

Question How can I use findscu for a query with the query/retrieve service?

Exclamation Here is an example: using findscu to query an image from a 
query/retrieve SCP using the patient root information model:

Code:
findscu -v -P -k 0008,0052="IMAGE" -k 0010,0020="300019" -k 0020,000D="1.2.3.1" 
-k 0020,000E="1.2.3.2" -k 0008,0018="1.2.3.3" localhost 104

Explanation:

    * -v runs the application in verbose mode
    * -P specifies to use the patient root information model
    * -k 0008,0052="IMAGE" tells the application that you are querying on image 
level (i.e. for an image)
    * -k 0010,0020="300019" is the patient ID of the patient in question 
(unique key on patient level)
    * -k 0020,000D="1.2.3.1" is the study instance uid of the study in question 
(unique key on study level)
    * -k 0020,000E="1.2.3.2" is the series instance uid of the series in 
question (unique key on series level)
    * -k 0008,0018="1.2.3.3" is the sop instance uid of the image in question 
(unique key on image level)
    * localhost is the machine the query/retrieve SCP is running on
    * 104 is the port the query/retrieve SCP is listening to.

Note that when you are querying on a certain query level (attribute 0008,0052 
set to either PATIENT, STUDY, SERIES or IMAGE), you have to specify all unique 
keys of levels which are above this level; e.g. on image level, you have to 
specify a patient id, a study instance uid and a series instance uid to denote 
the patient/study/series you are referring to, and of course you have to 
finally provide a sop instance uid to specify the image you are looking for.


*******************8

thus you do NOT have a valid dicom query because you do NOT have a 

* unique key on patient level

which must be the PATIENTID which we do not know.

I also tried to use only the patient ID  and no  name attribute:

here is the aeskulap output:

thus you need to review the definitions of the query levels carefully:

I should point out that i also corrected the people at osirix about this sort 
of thing
using the same test bed. :)

they  made similar errors initially too.

I stil think you should focus on display and comparison though.
