Following negative imaging of one variety or other, 12 units discontinued immobilization immediately, 10 continued until they were able to clear spines clinically, and the remaining five were prepared to discontinue if the patient's condition required it.
The combination of negative palpation of the axilla, negative imaging of the axilla and a negative sentinel node study would be taken as the criteria to avoid axillary clearance.
Distension of the uterine cavity could potentially modify internal uterine contour resulting in false-negative imaging of the uterine cavity especially in marginal uterine anomalies.
Among the 29 patients whom we presumed not to have osteomyelitis (the 13 who had negative Ga SPECT/CT imaging and no osteomyelitis on follow-up and the 16 who had a negative bone culture), 13 had negative imaging, for a specificity of 45% for imaging alone.
Review of the interval cancers detected clinically within a year of negative imaging showed 9 out of 11 were evident in retrospect by AWBU, and 1 of these was also evident in retrospect by mammography.
A combination of negative imaging, low LNR, low number of positive inguinal nodes, and no extracapsular extension (ECE) could accurately predict the absence of pelvic nodal involvement in 84 % of patients.
Our study showed an extremely high inter-observer agreement (K = 0.97) in the classification of carotid, vertebral and basilar arteries according to the Biffl grading system; this could be a consequence of the high percentage of negative imaging studies (96.3 %) in our patient population.
Other inventions included his "rayographs" (or photograms), which explored the potential of negative imaging by placing objects directly onto photo-sensitive paper then exposing them to light, and he was also an early adopter of light painting, exploring the technique with a penlight and camera in his Space Writings series.
In the event of a woman reporting symptoms during the screen examination, e.g., palpable lump or nipple secretion, the woman could be recalled in spite of negative imaging findings.
From Table 1, we also noticed that the overall quality index values of the negative imaging dark channel-based method [16] and that of the proposed method are closer and both are the higher and are 0.1278 and 0.1589, respectively.
Although this sensitivity is not comparable to echocardiography or CT for native aortic valve endocarditis, 18 F-FDG PET/CT can be used as a problem-solving tool in cases with high clinical suspicion and negative imaging, and in the detection of distant septic emboli (Table 2) [27, 28, 28].
