“…In patients with chronic cholecystitis, the thickness of the gallbladder wall is small, the gallbladder is clearly visible, and the gallbladder mucosal line is intact; lower bile duct obstruction occurs more frequently, and there is no small amount of abdominal effusion, liver invasion, and lymph node enlargement. Therefore, spiral CT can clearly distinguish the two diseases and lay the foundation for follow-up treatment [ 9 ].…”

To summarize the value of multislice spiral CT (MSCT) in the differential diagnosis of thick-wall gallbladder carcinoma (TWGC) and chronic cholecystitis (CC), the clinical data of 36 patients with TWGC and 60 patients with chronic cholecystitis who were treated in our hospital from January 2017 to May 2021 were retrospectively analyzed, and the CT image features and diagnostic accuracy of the patients were summarized. Compared with the CC group, the proportions of disruption of gallbladder mucosa line, blurred gallbladder outline, high obstruction of biliary tract, lymphomegaly, adjacent invasion, peritoneal effusion, wall nodules, and the gallbladder wall thickness in the TWGC group were higher, with statistical significance ( P < 0.05 ). Thirty-four patients with TWGC and 62 patients with chronic cholecystitis were diagnosed by MSCT. The sensitivity and specificity of MSCT in diagnosing TWGC were 86.11% and 95.00%, respectively. The positive likelihood ratio was 17.222 and the negative likelihood ratio was 0.1462. The positive prediction rate was 91.18%, the negative prediction rate was 91.94%, and the correct rate was 91.67%. MSCT can show the characteristic difference between TWGC and chronic cholecystitis, which can be used for differential diagnosis.

“…Volume perfusion CT has been shown to improve the detection of pancreatic insulinomas, particularly the ones which have transient hyperenhancement (comprising 30% cases)[ 60 , 61 ]. A recent study demonstrated that addition of low dose perfusion CT to contrast enhanced CT improved the detection rate of PNENs from 83.6% to 89.1% and found that blood flow parameters were significantly different between grade 1 and grade 2 tumors[ 62 ].…”

Gastroenteropancreatic neuroendocrine neoplasms comprise a heterogeneous group of tumors that differ in their pathogenesis, hormonal syndromes produced, biological behavior and consequently, in their requirement for and/or response to specific chemotherapeutic agents and molecular targeted therapies. Various imaging techniques are available for functional and morphological evaluation of these neoplasms and the selection of investigations performed in each patient should be customized to the clinical question. Also, with the increased availability of cross sectional imaging, these neoplasms are increasingly being detected incidentally in routine radiology practice. This article is a review of the various imaging modalities currently used in the evaluation of neuroendocrine neoplasms, along with a discussion of the role of advanced imaging techniques and a glimpse into the newer imaging horizons, mostly in the research stage.

“…However, chest radiography may predispose to underestimation of tracheal wall involvement, while the application of magnetic resonance imaging and positron emission computed tomography is associated with some limitations. Recent investigations have demonstrated that multi-slice spiral CT examination is a better technique for identification of intraluminal and extraluminal lesions [13]. It is also useful for evaluation of the extent and degree of infiltration of lesions into the cartilaginous ring.…”

Purpose: To determine the diagnostic value of multi-slice spiral computed tomography (CT) after adiponectin treatment of tracheal malignancies. Methods: Sixty patients with tracheal malignancies admitted to Emergency General Hospital from February 2017 to February 2021 were assigned to the study group. After physical examination, 60 healthy subjects in the same period served as the control group. All patients were treated with adiponectin. The control group was subjected to serum tumor marker testing before and after treatment, while the study group received multi-slice spiral CT before and after adiponectin treatment. Results: The 60 patients enrolled in the study group comprised 30 cases of squamous carcinoma, 22 cases of adenocarcinoma, and 8 cases of mucosa-associated lymphoma. Multi-slice spiral CT before treatment showed that 35 patients with tracheal malignant tumors had expansive lumen hyperplasia, while 25 patients with bulging tumors had saddle-like hyperplasia with irregular surfaces, uneven margins, and mean thickness of 5.96 ± 0.65 mm in the tracheal and bronchial walls adjacent to the luminal nodule. After treatment, the thickness of the tracheal and bronchial walls adjacent to the luminal nodule decreased to a mean value of 4.65 ± 0.48 mm. Prior to treatment, the mean enhancement value of contrast-enhanced CT was 18.98±1.23 Hu, and mean tumor diameter was 3.68 ± 0.23 cm. However, after treatment, the mean enhancement value increased to 25.98 ± 1.44 Hu, while mean tumor diameter decreased to 2.54 ± 0.20 cm in the study group. Conclusion: Multi-slice spiral CT has promising diagnostic value for patients with tracheal malignancies after adiponectin treatment. Therefore, it can potentially be used in the diagnosis of patients with tracheal malignancies.
