Comparison of standard-dose and half-dose dual-source abdominopelvic CT scans for evaluation of acute abdominal pain.

Comparison of standard-dose and half-dose dual-source abdominopelvic CT scans for evaluation of acute abdominal pain. Acta Radiol. 2018 Oct 30;:284185118809544 Authors: Lee KH, Shim YS, Park SH, Park SH, Choi SJ, Pak SY, Cheong H Abstract BACKGROUND: With the increasing number of computed tomography (CT) scans used for evaluation of acute abdominal pain, patient radiation exposure has increased rapidly. PURPOSE: To determine whether the diagnostic performance of half-dose abdominopelvic CT is non-inferior to that of standard-dose CT for patients with acute abdominal pain. MATERIAL AND METHODS: Ninety-eight patients with acute abdominal pain underwent dual-source abdominopelvic CT. Three sets of CT images were reconstructed: standard-dose filtered back projection (FBP); half-dose FBP; and half-dose sinogram-affirmed iterative reconstruction (SAFIRE3). Diagnostic performance of the standard-dose scan was compared with that of the half-dose scans by using a non-inferiority test with a 10% margin. The overall image quality was subjectively measured. RESULTS: Diagnostic performance for overall disease diagnosis with half-dose scans (area under the receiver operating characteristic curve [AUC] = 0.835 for FBP, 0.881 for SAFIRE3) was non-inferior to that of standard-dose FBP (AUC = 0.891) (95% confidence interval lower limit difference = -5.6% [half-dose FBP], -1.2% [half-dose SAFIRE3]). The diagnostic se...

A 44-year-old woman presented with lumbar pain (visual analog scale [VAS]  = 9) secondary to adrenocortical carcinoma sclerotic L4-vertebral metastasis. The positron emission tomography-computed tomography hypermetabolic lesion (Fig 1a,d) was unresponsive to radiotherapy or chemotherapy. She refused surgery. Following general anesthesia and aseptic preparation, 2 power d rill-mounted (Aesculap, Center Valley, Pennsylvania) k-wires were inserted in each vertebral pedicle with lateromedial opposite directions, resulting in crossed wires.

Forty-five of the 65 patients received salvage therapy. The median salvage PALN radiation dose was 54 Gy...

Authors: Sierra M, Alvarado M, Ramírez M, González L, Bueno S Abstract Hypercalcemia in hypoparathyroidism has rarely been described. A 55 year-old male patient with primary hypoparathyroidism, left eye melanoma, and Noonan's syndrome, was referred to the endocrinology clinics due to hypoparathyroidism. Laboratories showed serum calcium of 7.8 mg/d, and phosphate 4.8 mg/dl, while using calcium carbonate 1200 mg and vitamin D3 600 IU daily. Calcitriol 0.25 mcg daily was started and calcium carbonate discontinued. Abdominopelvic CT scan and thoracolumbar MRI, showed metastasis to liver, pancreas, and os...

The objective of this study is to report a very rare case who underwent surgical treatment of recurrent spinal phosphaturic mesenchymal tumor. The management of these unique cases has yet to be further elucidated. Patient concerns: A 52-year-old man presented with a 3-year history of back pain and 1-year history of continuous and progressive systemic bone pain. The patient, who had been diagnosed of TIO for 3 years, received surgical treatment of extended resection of spinal phosphaturic mesenchymal tumor at L5. Somatostatin receptor tomography revealed the expression of somatostatin in the spine increased significantly...

Authors: Zhao CG, Qin J, Wang X, Xu G, Jia Y, Guan YC, Mou X, Yuan H Abstract The aim of the present study was to compare the clinical outcomes of cage-shaped demineralized bone plus local bone grafts (CDBLG) with those of autogenous iliac crest bone grafts (ICBG) implanted for the treatment of single-level lumbar intervertebral disc degenerative diseases. A total of 69 cases of degenerative spinal disorder treated between January 2011 and December 2013 were retrospectively analyzed. Of these, 44 were treated with CDBLG and 25 with autogenous ICBG. All fusions were instrumented single level. Fusion was assessed aft...

Abstract An 87-year-old woman with a history of osteoporosis presented to the emergency department with complaints of low back pain and difficulty walking due to falling onto her left hip 2 weeks prior. Given the delay in diagnostic evaluation and persistent symptoms, computed tomography (CT) of the lumbar spine was ordered. The results of the CT were read as noncontributory and a physical therapist was consulted. Following examination, the physical therapist recommended left hip radiographs. A CT scan of the hip, which was ordered due to its superior specificity in detecting subtle fractures and to assist interve...
