Some CPG authors failed to fully disclose all financial conflicts of interest, and most guideline development panels and chairpersons had conflicts. In addition, adherence to IOM standards for guideline development was lacking. This study is relevant to CPG panels authoring recommendations, physicians implementing CPGs to guide patient care, and the organizations establishing policies for guideline development.

Hydroxyapatite deposition disease (HADD), or calcific tendinosis, is a common cause of atraumatic pain.Radiologists can be of great diagnostic assistance using imaging and clinical data to decipher HADD from other similar presenting pathologies such as infection, gout, trauma, and tumor. The radiologist should be aware of the various diagnostic imaging pitfalls and mimics of calcific tendinosis so that they may prevent further unnecessary workup and invasive procedures. In addition, radiologists should understand the role of percutaneous image-guided interventions as treatment options for HADD. The radiologist's understanding of the clinical presentation, imaging features, and treatment options of HADD will improve diagnostic accuracy and patient outcomes. PathophysiologyHADD is best described as pathologic deposition of calcium hydroxyapatite crystals in tendons, peritendinous
