In parallel to the quantitative DIR-based analysis, a qualitative analysis of serial post treatment chest CT examinations was performed by a board-certified fellowship trained radiologist with 10 years of experience in thoracic imaging. The classification system described by Lind et al [21 ] was applied, dividing the lung into three regions: apical-lateral, central-parahilar, and basal-lateral. For each region, parenchymal changes were graded as either 0/no change; 1/low opacity in linear streaks; 2/moderate opacity; 3/complete opacification; and summed over all regions to determine a total score. The radiologist was aware of the tumor location but blinded to the treatment protocol and all other analyses. Routine axial 2–3 mm thick CT images obtained with a standard soft tissue reconstruction kernel were reviewed on a clinical workstation (Agfa IMPAX, Agfa Healthcare, Canton, MA) using lung windows. All findings were compared to baseline CT images obtained before treatment.

All adult (> 18 years) patients who had a sinus CT scan, for any indication, between 1st January 2020 and 31st December 2021 at an inner-city hospital a liated with a tertiary university hospital were identi ed by the coding department. Of the identi ed patients, scans and case notes were analysed retrospectively. Data collected included age, gender, ethnicity, indication for CT scan (categorised to sinus or non-sinus disease), any documented relevant injury (head, nasal or facial trauma) and any previous ENT surgery. Patients were excluded if their scans had landmarks that were not clearly identi able to undertake the required measurements, or had a radiological or documented history of head, nasal or facial trauma, or any previous nasal surgical procedure. If patients had duplicate imaging over the study period, then only the earliest scan was included for analysis.
All included patients had their CT scans retrieved by the radiology department and reviewed on the hospital imaging platform (Agfa Impax, Agfa-Healthcare, Belgium). In order to evaluate septal insertions to the oor and roof of the nose, as well as overall septal asymmetry, the following measurements were conducted:
1. Angle between septum and maxillary crest (SMC) ( oor of nose) -left (LSMC) and right (RSMC) 2. Angle between septum and cribriform plate (SCP) (roof) -left (LSCP) and right (RSCP)

Brain MRI and MRA were performed using a Magnetom Espree 1.5T scanner (Siemens Healthcare GmbH) in Oulu, an Ingenia 1.5T scanner (Philips Healthcare) in Turku, and Avanto 1.5T scanners (Siemens GmbH) in Helsinki, Kuopio, and Tampere. The brain MRI protocol included the following pulse sequences: T1-weighted spin-echo (SE) sagittal, T2-weighted SE axial, T2-weighted fluid-attenuated inversion recovery axial, T1-weighted 3-dimensional inversion recovery SE coronal, axial diffusion-weighted imaging (DWI), and 3-dimensional time-of-flight MRA. After administering gadolinium contrast agent (0.2 mL/kg) (Dotarem; Guerbet), T1-weighted SE axial and T1-weighted SE coronal sequences were conducted.
Viewing applications for diagnostic radiology, which comprised picture archiving and communication systems or digital imaging and communications in medicine, were used to evaluate the MRI scans, namely, neaView (Neagen) in Oulu, Sectra Workstation IDS7 version 19.1.10.3584 (Sectra AB) in Kuopio, and Agfa Impax version 6.6.1.5551 2017 (Agfa Healthcare N.V.) in Helsinki. Radiologists from 3 hospitals evaluated the MRI scans, all of which were reevaluated by M.S.-P.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
