The microspheres may contain various ingredients. E.g. perflutren suspension in
microspheres of phospholipids is classified in QV08DA04.
Perflenapent covers structural isomers of dodecafluoropentane i.e. perflisopent.

DIAGNOSTIC RADIOPHARMACEUTICALS
An expert group consisting of Dik Blok (the Netherlands), Per Oscar Bremer
(Norway) and Trygve Bringhammar (Sweden) is responsible for the ATC
classification of radiopharmaceuticals in V09 and V10. The group has also prepared
guidelines on the classification of these products.
Radiopharmaceuticals for diagnostic use are classified in this group, while those for
therapeutic use are classified in QV10. In general, 3rd level groups are defined by
site of action or organ system, 4th level groups according to the radionuclide, while
the 5th level code specifies the chemical substance involved. The ATCvet 5th level
code defines the actual form essential in nuclear medicine procedures, which
includes radionuclide and carrier molecule. Consequently, products on the market,
which can often be regarded as intermediate products rather than ready-to-use
radiopharmaceuticals, can be given more than one (5th level) ATCvet code, e.g.
technetium ( 99m Tc) exametazime (QV09AA01) and technetium ( 99m Tc) labelled
cells (QV09HA02).
ATC codes are not assigned for radionucleotide precursors which are used only in
the radiolabelling of another substance prior to administration.
