“…Multiplanar images display anatomic features in a frontal view fashion and have been found to enhance the usefulness of cross-sectional imaging modalities, such as CT and MRI. [5][6][7][8] Because of the more natural anatomic relationships depicted in these reformations, radiographic images may now be easier for laypersons to comprehend, making them more useful for counseling.…”

Almost all patients reported comprehension of images, improvement in understanding because of review of images, and preference for being shown images. Female patients expressed greater understanding and preference for all patients to be shown their images. Review of radiographic images represents a potentially useful additional modality for patient counseling whose usefulness for improving satisfaction will need to be confirmed in further studies.

“…However, section thickness has a significant effect on bias and precision, particularly for smaller nodules. In this study, the measurements obtained using the 0.625-mm section thickness were superior, with minimal bias and maximal precision across all reference-standard diameters [23]. Use of the 5.00-mm section thickness yielded inferior measurements for 5.00-mm and smaller nodules [24].…”

We did this study to investigate the effect of thick (5mm) and thin (1 or 0.625 mm) slice thickness of CT images on evaluating pulmonary nodules' growth to improve their diagnostic accuracy. The clinical and CT data of 251 patients with lung nodules and two follow-up CTs from October 2016 to October 2019 were analyzed retrospectively. Malignant nodules were confirmed by pathology, and benign nodules were confirmed by pathology or follow-up. Two radiologists double-blindly assessed the CT features (density, shape, lobes, border), maximum diameter, and volume of nodules on the thick (5MM) and thin (≤1MM) images of two follow-up CTs. We use One-way analysis of variance for quantitative data; the X2 test or FISHER exact probability method was used for qualitative data; and the ROC curve was used to analyze the diagnostic power of nodule size, volume, and change in differentiating benign and malignant lesions. Among 251 pulmonary nodules, 117 (46.6%) benign nodules and 134 (53.3%) malignant nodules. During the CT follow-up, the volume measured on the thick-section image, the diameter, and the volume measured on the thin-section image were statistically different in benign and malignant lung nodules (P<0.001). In contrast, the diameter measured on the thick-section image was similar between these two groups (P=0.328). For benign and malignant pulmonary nodules, the diameter, volume, and change measured on the thin-section image were significantly larger than the thick-section image's data (P<0.001). The ROC curve showed that the diagnostic efficiency of volume was higher compared to the diameter. There were significant differences in nodule type, density change, shape, lobulation, and pleural retraction between benign and malignant nodules for CT features. Accurately assessing the volume changes combined with CT characteristics will help improve lung nodules' diagnosis accuracy. Volume measured on thin-section (1mm) CT images is the best quantitative parameter for assessing the change of pulmonary nodules. Combining Volume change with CT characteristics would help to improve the diagnostic accuracy.

“…Of those cases exhibiting distant metastases, pulmonary metastases were most common (51.9 per cent). It should be noted that sensitivity of CT for detecting pulmonary nodules less than or equal to 5 mm in diameter is 22–89 per cent (Angelelli and others 2008), so the possibility remains that the patient in the present case exhibited undetected metastatic disease at initial presentation.…”

Temporal bone partial ostectomy via the temporomandibular joint to treat osteosarcoma of the caudal zygoma in a three‐year‐old Labrador retriever

A three years, seven-month-old male entire Labrador retriever was referred with a one-month history of pain when yawning and eating. CT revealed a 20×10×10 mm mass in the region of the left caudal zygoma. CT-guided biopsy results identified a florid periosteal reaction but were otherwise inconclusive. Surgery was performed to resect the left caudal zygoma via the temporomandibular joint. Further histopathological results confirmed completely resected osteogenic osteosarcoma with narrow margins. No other treatment modalities were pursued. The dog remained free from clinical signs until 28 months following surgery when local tumour growth and thoracic metastases were diagnosed.
