Urgent Multidetector Computed Tomography in Colon Cancer: Postsurgical Changes and Early Complications.

Complications after surgery for colorectal cancer are common in emergency departments. Multidetector computed tomography plays a fundamental role in the follow-up of patients after surgery, because it enables the detection of relapse and complications. Radiologists need to be familiar with different surgical techniques and the normal postsurgical changes so that we can differentiate them from potential complications and relapse.

Gynecological pelvic pain as emergency pathology.

Acute pelvic pain is a common condition in emergency. The sources of acute pelvic pain are multifactorial, so it is important to be familiar with this type of pathologies. The purpose of this article is review the main causes of gynecological acute pelvic pain and their radiologic appearances to be able to make an accurate diagnosis and provide objective criteria for patient management.

Yield of Computed Tomography at Baseline Staging of Melanoma.

Background: Current guidelines call for baseline imaging only for very high-risk (T4b) primary cutaneous melanomas.

Objectives: To estimate the frequency of computed tomography (CT) at baseline staging of primary cutaneous melanoma and the diagnostic yield of CT; and to describe the types and frequencies of incidentaloma findings.

Material And Methods: Cross-sectional study of cutaneous melanoma cases (tumor classifications Tis to T4bN0M0) attended between 2008 and 2014 in a specialized melanoma unit.

[Doppler ultrasonography of scrotal injury].

Objectives: To review the current body of knowledge about performing, understanding, and interpreting Doppler ultrasonography in scrotal injury.

Material And Methods: 17 patients with scrotal injury were studied. We describe the ultrasound technique and a wide spectrum of traumatic pathology together with its complications, analyzing the ultrasonographic signs and Doppler flow patterns that can orient the diagnosis and approach to treatment.
