Clinical trials were his bread and butter, and leading guideline writing groups became his passion. The most memorable take-home message for me was this: Before you do any test, a clinician should ask themselves, ‘Will this change management? And if so, how?’ A clinician should know what they will do if the test is positive or negative and be able to articulate that. Sadly, this is not always the case. And whilst it might be ‘nice to know’, the cost of confirmatory tests is certainly not insignificant.&lt;/p&gt;&lt;p&gt;When I trained in ultrasound, we still called it ‘diagnostic ultrasound’ to differentiate it from therapeutic ultrasound, but this also highlighted the immense and unique diagnostic properties of ultrasound. Increasingly, ultrasound is used to not only diagnose, but also to monitor and screen for conditions, as well as to aid in management and prognosis. While all of these are laudable uses, I still think it is helpful when we can link our imaging directly to change in management.&lt;/p&gt;&lt;p&gt;In this issue of AJUM, Smith and Mistry&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; present research documenting the impact of formal echocardiography (echo) on patient management in a small clinical audit of formal echos in their intensive care unit (ICU). Although half of the patients had critical findings found on formal echo, only 25% resulted in management change. Perhaps, the remainder of the critical findings were either already suspected, and therefore being treated; or had been anticipated. Indeed, it is possible that a point of care ultrasound (POCUS) had already given them some clinical cues, and thus, the formal echo was simply confirmatory. In a reasonable number of patients, the formal echo helped make the decision to proceed with palliation and this seems an entirely reasonable reason to do an extra imaging test.&lt;/p&gt;&lt;p&gt;Also, in the ICU setting, Xin &lt;i&gt;et al&lt;/i&gt;.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; report on the use of Tissue Doppler Imaging (TDI) of the diaphragm to optimise the timing of weaning from mechanical ventilation in ICU patients. Using TDI to measure the low velocity motion of heart muscle is fundamental to echocardiography, so the extension to the diaphragm seems a logical extension of practice. But a good idea still needs to be tested and shown to aid patient management. Innovation needs to be effective.&lt;/p&gt;&lt;p&gt;Innovation is a key part of medicine, and finding new applications for imaging is part of that.
