Perhaps you are thinking of enrolling in a higher research degree? Or you have an idea for a project you've been wanting to get off the ground? Maybe you are sitting on a database that is just waiting to be transformed into a paper that has the potential to explain, inform or, indeed, change practice? If any of these resonate with you, then I encourage you to begin your next, or indeed first, research project.</p><p>Every research project starts with a research question, but the methods used vary depending on that question. The study design and approach will be defined by the question, and it is important to remember that there is no one way to undertake ultrasound research. There are many different study approaches: from audits and educational research to outcomes research.</p><p>All research starts with data. In this issue of AJUM, Moore <i>et al</i>.<span>¹</span> take you through the steps needed to mine data from an imaging archive. Most of us have a digital database of images, measurements and reports, but extracting those data in a consistent way, especially when there are free text fields, is not as straightforward as one would think.</p><p>When little is known about a condition, research often takes the form of clinical audit of cases or case series. We have three distinct examples of this in this AJUM issue: Hosokawa <i>et al</i>.<span>²</span> compare the detection of submandibular sialoliths by ultrasound with magnetic resonance imaging (MRI) and computed tomography (CT), while Boman <i>et al</i>.<span>³</span> present a small case series demonstrating a potential role for ultrasound to detect small vessel inflammation as a pre-curser to rheumatic vasculitis. Lastly, Walsh and Lees<span>⁴</span> present a clinical audit of over 3000 consecutive routine mid-semester obstetric scans and report the proportion of major and minor abnormalities. There are two important points to note within this study, which speak to the veracity of the data: this is a single operator clinic such that the ultrasound approach was likely consistent over the time period, and they included consecutive patients. Clinical research should be undertaken using consecutive patients, which ensures all eligible patients are recruited. When non-consecutive, or convenience, sampling is used, I often wonder why they were excluded. Because of image quality? Because their results were outliers—not aligned to the researchers' bias?</p><p>It is often said that the strongest form of evidence, after the randomised clinical trial, is meta-analysis or systematic review because all the available evidence is presented in a summative and unbiased manner.
