The want to do a reverse shoulder replacement, I don't?

CT Dose:                                                              
As required by California law, the CTDIvol and DLP radiation doses    
associated with this CT study are listed below. This represents the   
estimated dose to a standard lucite phantom resulting from the        
technique used for this study, but is not the dose to this specific   
patient.                                                              
Type / CTDIvol / DLP / Phantom                                        
Helical / 33.05 / 839.31 / B                                          
Total Exam DLP: 839.31                                                
CTDIvol = mGy             DLP = mGy-cm                                
Phantom: B=Body32, H=Head16                                           
                                                                      
FINDINGS:                                                             
No acute fracture or dislocation. Moderate arthritic changes          
glenohumeral joint with juxta-articular spurring. Defects in the      
humeral head and proximal diaphysis may be from removal of prior      
surgical hardware. Small glenohumeral joint effusion suggested.       
Widening of the acromioclavicular joint may be from degenerative or   
inflammatory arthropathy or prior surgery. 4 mm calcification         
projecting superior to humeral head support calcific tendinitis. No   
axillary adenopathy. Visualized right lung appears clear.             
Degenerative changes noted visualized cervical spine. Ectasia         
ascending thoracic aorta measuring about 3.9 cm.
